Note:

This thesis presents a system for automating the design of magnetic devices such as induction motors, transformers, and alternators. The search space of possible designs is parameterized using a universal representation of devices which basically specifies the distribution of material at every point in space. The design specifications are input in the form of a mathematical function, design is performed by optimizing this objective function. Output consists of a set of grey-scale pixel-like images of the distribution of the different materials in the device. From the perspective of artificial intelligence, the system is based on the first principles of magnetic devices, i.e. Maxwell's equations. Since no other know ledge is embedded in the system, it has the potential of discovering original devices to solve long-standing design problems, and also to solve design problems for which no human expertise exists.

Cette thèse présente un système automatique de conception de dispositifs électromagnétiques tels que les moteurs asynchrones, les transformateurs et les alternateurs. L'espace de faisabilité est paramétrise par une représentation universelle des dispositifs dont les matériaux constitutifs sont indiqués à chaque point dans l'espace. Les données sont fournies sous forme d'une fonction mathématique qui représente les spécifications du dispositif, et la conception automatique est accomplie par l'optimisation de cette fonction objective. La sortie du système est un ensemble d'images en différents tons de gris qui représentent la disposition des matériaux constitutifs du dispositif. Du point de vue de l'intelligence artificielle, le système est fondé sur les premiers principes de la théorie des dispositifs magnétiques, c'est à dire les équations de Maxwell. A part de ces premiers principes, aucune autre connaissance n'est incluse dans le système. Ce dernier a donc la capacité de trouver des conceptions originales à la solution des problèmes classiques, il peut également résoudre des problèmes de conception pour lesquels il n'y a aucune expertise humaine.

▼ The field of molecular magnetism has expanded rapidly since the discovery of single molecule magnets (SMMs) in the 1990?s and has witnessed extraordinary advances in the last several decades. One of the current trends in molecular magnetic research is to incorporate metal ions that have pronounced single-ion anisotropy in an effort to improve magnetic exchange interactions. The 4d and 5d transition metal ions have large spin-orbit coupling parameters which contribute to the orbital angular momentum effects that lead to anisotropic behavior. The work herein describes efforts to synthesize and characterize new cyanide-bridged molecular materials incorporating 4d and 5d transition metal ions, specifically the [Os(CN)_(6)]^(3-), [Mo(CN)_(6)]^(3-) and [W(CN)_(8)]^(3-) ions. The 5d hexacyanometallate [Os(CN)_(6)]^(3-) was incorporated into a trinuclear cyanide bridged molecule and the [Fe(CN)_(6)]^(3-) analog was prepared as a reference compound for assessing the effect of the 5d versus 3d metal ion on the magnetic properties. Both molecules exhibit SMM bistability with a pronounced increase (~90 %) in the blocking temperature (TB) of the OsIII analogue. In addition to typical SMM behavior, both compounds exhibit exchange-biased SMM behavior, a shift in the quantum tunneling of the magnetization (QTM) from zero field. This exchange-bias can be turned ?on? or ?off? depending on the presence of interstitial methanol molecules. New trigonal bipyramidal (TBP) molecules incorporating the rarely studies hexacyanomolybdate(III) ion are presented in chapter III of this dissertation. The molecules of general formula [M(tmphen)_(2)]_(3)[Mo(CN)_(6)]_(2) (M = V^(II), Mn^(II) and Fe^(II); tmphen = 3,4,7,8-tetramethyl-1,10-phenanthroline), represent additions to a large homologous family of TBP molecules reported by the Dunbar group over the years. The [Mo(CN)_(6)]^(3-) ion was prepared in situ by loss of one cyanide ligand from [Mo(CN)_(7)]^(4-). Of particular interest among the compounds reported is the V_(3)Mo_(2) analog which exhibits extraordinarily strong antiferromagnetic coupling (estimated J = -134 cm^(-1). The observed exchange coupling parameter is more than twice the current record for the antiferromagnetic coupling parameter for a cyanide-bridged magnetic molecule. Another set of results were obtained using the octacyanometallate anion [WV(CN)_(8)]^(3-) as a building block for the synthesis and magnetic studies of a family of new cyanide-bridged magnetic materials. The compounds exhibit several different structural motifs including three 0-D molecular compounds (two pentanuclear molecules and a linear trinuclear molecule) and a 1-D chain, findings that illustrate the structural versatility of the octacyanotungstate(V) ions. The TBP molecule, [Mn(tmphen)_(2)]_(3)[W(CN)_(8)]_(2), exhibits evidence for an out-of-phase signal when subjected to ac measurements in zero applied field. The 1-D chain also reveals evidence for the beginning of an out-of-phase signal under zero applied field which hints at single… Advisors/Committee Members: Dunbar, Kim R.

▼ The primary focus of this dissertation is using inelastic neutron scattering (INS) to probe magnetic excitations in paramagnetic complexes including single-molecule magnets (SMMs). Other related studies include the following: (1) Simulating vibrational frequencies to understand spin-phonon coupling (SPC) in a single-molecule magnet; (2) Using quasi-elastic neutron scattering (QENS) to study molecular dynamics of a paramagnet. Zero-field splitting (ZFS) parameters (axial: D and rhombic: E) of metalloporphryins Fe(TPP)X [X = F, Br, I; H2TPP = tetraphenylporphyrin] have been directly determined by INS. These studies provide a complete determination of ZFS parameters for a metalloporphryin halide series demonstrating that D increases from F to I complexes. Ab initio methods were led to the understanding of the origin of the halide trend. INS has also been used to probe several Co(II) and an Er(III) SMMs. The magnetic excitations were determined by a variety of methods demonstrating that INS is a unique technique to determine the magnitude of these excitations. Most prominently, INS conducted under variable magnetic fields, reveals magnetic excitations in single crystals and powder samples in the energy region above 40 cm-1. In addition, this work shows a unique strength of INS to show the origin of spin-phonon entangled peaks at 0 T. Vibrational frequencies and simulation of atomic displacements in Co(II) SMMs have been calculated via ab intio methods to study SPC. Raman spectroscopy of Co(acac)2(H2O)2 (acac = acetylacetonate), Co(acac)2(D2O)2 and Co(acac-d7)2(D2O)2 gives experimental SPC constants of different magnitudes. By probing the displacements in atoms in the SMMs, a correlation between the largest bond angle change in the first coordination sphere and largest SPC constant has been discovered. This work leads to understanding of how the electron spins in the Co(II) complexes interact with phonons in the energy region near the magnetic excitation. QENS has been used to study methyl rotation in Co(acac)2(D2O)2, which behaves as a paramagnet in the temperature range probed (80–100 K). The use of external magnetic fields leads to the observation of field-dependent methyl rotation. This field-dependent behavior sheds light on intermolecular interactions in the solid state.

▼ The UK Committee on Radioactive Waste Management (CoRWM) recommended, in 2006, that geological disposal coupled with safe and secure interim storage should have been the way forward for the long-term management of the UK’s higher activity wastes. The design of the underground repository contemplates the presence of bentonite plugs to seal access galleries and deposition boreholes and hence the interaction between the clay-based backfill material and the underground water. Remote monitoring of the fluid saturation of the barrier, the waste canisters and of the surrounding subsurface Geological Disposal Facility environment assumes a relevant importance to guarantee the safety of the repository and to increase the confidence and the reliance of the communities living in areas potentially affected by the repository over time. This remote monitoring of the Engineered Barrier System represents a technical challenge due to the unsuitability of some of the traditional geotechnical techniques or to the intrinsic unreliability of many geophysical prospecting techniques in providing information about the evolution of the Thermo-Hydro-Mechanical-Chemical coupling of the system over long timescales up to and including post-closure evolution. In this project, I offer an initial approach to an innovative way of using mineral magnetism, and, in particular, I analyse the possible exploitation of corrosion-induced variations of the magnetic properties of several magnetic materials to monitor water saturation in the Engineered Barrier System and its evolution through time. Initially the reactivity of several natural and synthetic materials is tested under different “extreme” conditions to analyse the feasibility of the research concept and identify the materials more adapt to carry out the job. The effects that the corrosion of the magnetic materials has on the clay matrix is also analysed in detail throughout all the thesis work. The initial tests lead to the identification of specific transitions in the hysteretic behaviour of three of the initial candidates (Nd-Fe-B, AlNiCo and SmCo alloys). These three materials are subsequently tested under conditions closer to a real “evolved” Barrier System, where the groundwater interacts, with cementiferous grout producing hyperalkaline leachates. The final tests consider the temporal evolution (after 4, 8 and 12 months) of the magnetic properties of these materials in a dysoxic environment under imposed fluid-flow. The results show a clear change in the hysteretic properties of the three materials analysed and the feasibility of the monitoring of the Barrier fluid saturation in the short-term. Furthermore, the corrosion of the magnets, under the conditions applied, did not cause formation of non-swelling clays.

▼ Modern society s propensity for miniaturized end-user products is compelling electronic manufacturers to assemble and package different micro-scale, multi-technology components in more efficient and cost-effective manners. As the size of the components gets smaller, issues such as part sticking and alignment precision create challenges that slow the throughput of conventional robotic pick-n-place systems. As an alternative, various self-assembly approaches have been proposed to manipulate micro to millimeter scale components in a parallel fashion without human or robotic intervention. In this dissertation, magnetic self-assembly (MSA) is demonstrated as a highly efficient, completely parallel process for assembly of millimeter scale components. MSA is achieved by integrating permanent micromagnets onto component bonding surfaces using wafer-level microfabrication processes. Embedded bonded powder methods are used for fabrication of the magnets. The magnets are then magnetized using pulse magnetization methods, and the wafers are then singulated to form individual components. When the components are randomly mixed together, self-assembly occurs when the intermagnetic forces overcome the mixing forces. Analytical and finite element methods (FEM) are used to study the force interactions between the micromagnets. The multifunctional aspects of MSA are presented through demonstration of part-to-part and part-to-substrate assembly of 1 mm x 1mm x 0.5 mm silicon components. Part-to-part assembly is demonstrated by batch assembly of free-floating parts in a liquid environment with the assembly yield of different magnetic patterns varying from 88% to 90% in 20 s. Part-to-substrate assembly is demonstrated by assembling an ordered array onto a fixed substrate in a dry environment with the assembly yield varying from 86% to 99%. In both cases, diverse magnetic shapes/patterns are used to control the alignment and angular orientation of the components. A mathematical model is used to characterize part-to-substrate MSA. It is shown that the assembly rate and the yield are most dependent on the rotational symmetry of the magnet pattern. Simultaneous and sequential heterogeneous assembly of two types of parts with selective bonding is also demonstrated, with the average assembly yield of 93% in 60 s and 99% in 3.5 min respectively. Finally, MSA with functional electrical interconnects is also demonstrated with a yield of 90.5%.

▼ In this thesis we have developed electronic and spin model Hamiltonians to understand magnetism in molecule based magnets like photomagnets, high-nuclearity transition metal complexes and single molecule magnets. In chapter 1, we provide an overview of molecular magnets. Here, we present a survey on the literature available on molecule based magnets. The chapter throws light on various phenomena found in molecular magnetic systems that range in dimensions from 3D down to molecular dimension. This is followed by a brief introduction to high-nuclearity transition metal complexes and single molecule magnets (SMMs). In the last two sections of this chapter, we discuss Light Induced Excited Spin State Trapping (LIESST) and photomagnetism in some molecular systems. Chapter 2 discusses various theoretical models that have been developed for magnetism. We begin with an introduction to the spin Hamiltonian and the origin of direct and kinetic exchange in simple systems and extend it to larger systems. Then we introduce the concept of superexchange proposed by Goodenough and Kanamori, followed by introduction to anisotropic Dzyalashinskii-Moria (DM) exchange and Ruderman-Kittel-Kasuya-Yosida (RKKY) interactions. We also discuss molecular magnetic anisotropy, long-range magnetic interactions and higher order exchange interactions. These are effective model Hamiltonians that do not provide microscopic origin of magnetism, hence electronic model Hamiltonians need to be invoked. We introduce electronic model Hamiltonians like Huckel, Hubbard and Pariser-Parr-Popple (PPP) models and then present numerical techniques like valencebond (VB) and constant MS techniques that are used to exactly solve these model Hamiltonians. We present a many-body electronic model involving the active orbitals on the transition metal ions for photomagnetism in MoCu6 cluster, in chapter 3. The model is exactly solved using a valence bond approach. The ground state solution of the model is highly degenerate and is spanned by five S=0 states, nine S=1 states, five S=2 states and one S=3 state. The orbital occupancies in all these states correspond to six Cu(II) ions and one diamagnetic Mo(IV ) ion. The optically excited chargetransfer (CT) state in each spin sector occurs at nearly the same excitation energy of 2.993 eV for physically reasonable parameter values. We find that the excitation cross sections in different spin manifolds are similar in magnitude. The lifetime of the S=3 excited states is expected to be the largest as the number of states below that energy is very sparse in this spin sector compared to other spin sectors. This shows that photomagnetism is not due to preferential excitation to the S = 3 state. The inputs from the electronic model allows us to develop a kinetic model. In this model, photomagnetism is attributed to a long lived S=3 charge transfer excited state for which there appears to be sufficient experimental evidence. Based on this postulate, we model photomagnetism by including internal conversions and intersystem… Advisors/Committee Members: Ramasesha, S.

▼ Broken inversion symmetry in a crystal lattice allows an extra term called the Dzyaloshinskii-Moriya (DM) interaction in the magnetic Hamiltonian. The DM interaction tends to align spins in perpendicular orientation and therefore competes with the exchange interaction that favors collinear spins. This competition results in different modulated chiral magnetic structures depending on the relative strength of the two interactions. Skyrmion, soliton and magnetic blue phases are some of the anticipated structures. This dissertation extends the search for these exotic magnetic structures using various techniques to study the magnetism in the noncentrosymmetric magnets Cr11Ge19 [chromium eleven germanium nineteen], Cr1/3NbS2 [chromium one-third niobium disulphide] and K2V3O8 [fresnoite-type potassium vanadate]. Experimental investigations of magnetic, thermal, structural and elastic properties of Cr11Ge19 indicate complex itinerant ferromagnetism, evidence of spin wave excitations, and strong magnetoelastic coupling in this material. First principles calculations support the presence of itinerant ferromagnetism and suggest a noncollinear ground state may be expected. In the chiral helimagnet Cr1/3NbS2 the magnetic transition is found to strongly affect the electrical transport. Spin reorientation from the helimagnetic ground state to the commensurate ferromagnetic state is evident in the magnetoresistance. Neutron scattering is used to demonstrate the change in the periodicity of the incommensurate structure and the eventual incommensurate to commensurate transition, in accordance with the theoretical prediction of the soliton model. The tetragonal easy axis antiferromagnet K2V3O8 has been investigated by DC magnetization, AC susceptibility and heat capacity measurements. Based on the comparison of the behaviors observed in these measurements with other well-studied chiral helimagnets, the existence of two different spiral structures - one parallel and one perpendicular to the c axis - is proposed.

▼ Electromagnets play an important role in everyday life from motors and generators to such devices as Magnetic Resonance Imaging (MRI). The larger a magnetic field needed in such a device the more demand there is in power consumption and space. The development of superconductors (SC) and their ability to dissipate negligible power has made it possible to create larger fields in a more cost effective and space efficient manner. The disadvantage of the SC is that it needs to be operated at cryogenic temperatures (typically below 110 K). Cryogenics is a significant cost factor so the less power needed for cooling a SC magnet the more cost effective the system can become. The main heat load comes from the ohmic dissipation of the current leads necessary to energise the magnet. The current leads provide the electrical connection from the power supply at room temperature to the coils in the cryogenic environment. To circumnavigate this heat load a superconducting device known as a flux pump (FP) can be embedded in the cryogenic environment. The flux pump operation can be generalised as a DC generator, which minimises ohmic heating and makes the power supply needed to energise the magnet superfluous. HTS 110 is a magnet manufacturer who has assigned the task of implementing a flux pump into a commercial magnet application and developing a complete system capable of controlling a homogenous current level in their magnets. Such a flux pump module was developed and successfully incorporated into an existing SC magnet. This thesis details the mechanical design, control hardware, required software used to create this technology and the benefits it presents. Compared to the current lead technology, the developed flux pump module reduced the heat load on the cryo-cooler by almost a factor of 5. In addition a produced magnetic field of 750 mT was achieved, which corresponds to a current of 68 A in the magnet coils. Such a high field could not have been obtained in the present setup with conventional technology. The large heat load caused by current leads would increase the overall temperature of the coils and in turn decrease the current capability of the circuit to approximately 20 A, resulting in a field that is more than three times smaller. A full control system using field strength as feedback to control the rotation of the FP was implemented. This included an iterative hardware design and fabrication process followed by software implementation, that led to a high level system encompassing a PID type control algorithm. The control system achieved a field stability of 30 parts per million (PPM) which puts the system in reach for the needed NMR stability criterion of 1 PPM.

▼ A skyrmion is a vortex-like spin pattern which has been observed in so-called B20 magnetic systems such as MnSi, (Mn,Fe)Si and a few other metallic magnets as well as in insulating Cu₂OSeO₃. We conduct a comprehensive study of muon spin relaxation (μSR) on bulk single crystals of MnSi and (Mn,Fe)Si, a MBE thin film of MnSi, and a ceramic specimen of Cu₂OSeO₃ in this work. The generic second-order like phase transition indicated by 1/T₁ peaks at T_c in bulk systems is discussed in light of the Brazovskii-type first-order phase transition due to the presence of the DM interaction. We also discuss the different temperature dependences of μ⁺ spin-lattice relaxation rate 1/T₁ in bulk pure systems MnSi and Cu₂OSeO₃ and their commonalities in the paramagnetic state and the ordered state due to the DM interaction. Furthermore, we highlight the enhanced 1/T₁ in the skyrmion crystal (SkX) phase compared to neighboring conical phases due to an abundance of low-energy magnetic fluctuations/excitations. This abundance is corroborated by the reduced static order parameter in the SkX phase of MnSi compared to neighboring conical phases, deduced by combining μSR experiments and magnetic field simulations. The intermediate (IM) region above T_c, where the modification of magnetic transition by the DM interaction starts to appear in MnSi, exhibit multi-time scale spin fluctuations, topologically non-trivial Hall resistivity and non-Fermi-liquid exponent of longitudinal resistivity in single-crystal Mn₀.₉Fe₀.₁Si and the MnSi MBE thin film, similar to the magnetically disordered phase of pure MnSi under hydrostatic pressure. These three defining features indicate a fluctuating skyrmion liquid in this magnetically ordered state, stabilized by pressure, disorder or reduced dimensionality. Moreover, the magnetic transition is strongly first order in the MnSi MBE thin film sample, different from the Brazovskii-type weakly first order transition in bulk samples, suggesting the importance of reduced dimensionality in modifying the nature of magnetic phase transitions in B20 systems.

Neste estudo, as propriedades magnéticas dos ímãs sinterizados, produzidos a partir de uma mistura de ligas Pr16Fe76B8 e Pr14FebalCo16B6Nb0,1Mx, onde M= Al, Cu, P, Si, Gd, Ga, Dy, Tb e x= 0,1, 0,3, 0,5 % at. em iguais proporções, foram correlacionadas com as características microestruturais através de microscopia eletrônica de varredura (MEV) e de transmissão (MET). Utilizou-se microscopia eletrônica de varredura (MEV) e processamento computacional das micrografias, na investigação das características associadas ao tamanho e formato dos grãos magnéticos (Φ). A correlação utilizada indicou que fatores de quadratura superiores estão associados a grãos mais arredondados e com distribuição de tamanho mais estreita. Considerando que a variação no tamanho de grão e os valores de coercividade não se mostraram conclusivas com MEV, utilizou-se o recurso da microscopia eletrônica de transmissão (MET), microanálise com EDS e padrão de difração eletrônica. A associação da coercividade com a microestrutura foi feita com base nas investigações das fases não magnéticas, ricas em praseodímio dos pontos triplos e nos contornos de grãos. Com o microscópio de transmissão de alta resolução (HRTEM), foi possível observar a presença de uma camada contínua e regular entre os grãos da fase magnética para o ímã com adição de Ga 0,25% at. A modificação da microestrutura no contorno de grão do ímã com adição de Ga pode ser indicada como responsável pelo aumento de 10% na coercividade (1100 mT) comparado com o ímã Pr15FebalCo8B7Nb0,05.

In this study the magnetic properties of sintered magnets, prepared with a mixture of Pr16Fe76B8 and Pr14FebalCo16B6Nb0.1Mx alloys, where M = Al, Cu, P, Si, Gd, Ga, Dy, Tb and x = 0.1, 0.3, 0.5 at.% in the same proportions, were correlated with the microstructural features by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). SEM and computer processing of the micrographs were used in order to provide the characteristics associated with the size and shape of the magnetic grains (Φ phase). The correlation used shows that superior squareness factors are associated with rounder and narrower size distribution grains. Considering that the variation in the grain size and coercivity values were not conclusive with SEM, it has been used TEM, micro analysis by EDS and electron diffraction pattern. The coercivity relation with the microstructure was based on investigations of non-magnetic phases, in triple points, and in the grain boundary. With a high resolution transmission microscope (HRTEM), it was possible to observe a regular and continuous layer between the grains of the magnetic phase for the magnet with 0.25 at.% of Ga. The presence of such boundary can be indicated as responsible for higher coercivity values of this magnet. Microstructure was modified in the grain boundary by Ga addition and can be indicated as responsible for coercivity value (1100 mT) 10% higher than Pr15FebalCo8B7Nb0.05 magnet.

▼ This dissertation describes structural and magnetic studies of three-dimensional Prussian Blue analogs (PBAs), one-dimensional single chain compounds, and discrete ?zero-dimensional? molecules. All compounds that were studied are members of a large class of materials known as molecular nanomagnets which exhibit a barrier to spin reversal due to magnetic anisotropy which can surpass the superparamagnetic limit of classical materials. Single-molecule magnets (SMMs) which can exhibit long-lived relaxation times for their magnetic states are the prototype for the field and are poised for implementation in next generation nanoelectronic devices. The goal of this dissertation research was to determine sources of anisotropy in the quest for interesting magnetic properties. Prussian Blue, FeIII4[FeII(CN)6]3?16H2O, exhibits ferromagnetic coupling with a Curie temperature of approximately 5 K. Different synthetic attempts historically yield slightly different formulations of the compound. We have revisited the structural analysis of this compound and have obtained the first crystal structure of Turnbull?s Blue, KFeIII[FeII(CN)6]. Capping ligands can reduce the dimension of PBAs while retaining their interesting properties. This strategy is presented by the reactions of tptz (tptz = 2,4,6-tris(2-pyridyl)-1,3,5-triazine) complexes of Cu(II), Co(II), and Fe(III) with [MV(CN)8]3- (M = Mo, W) anions which led to three new heterobimetallic chains based on ladder- or square structural motifs. The compound {[FeIII(tptz)WV(CN)8]?2CH3OH}? exhibits weak out-of-phase AC signals at low temperature, which indicates single-chain magnet behavior. The blocking of all open coordination sites results in discrete molecules with the potential for SMM behavior. Underexplored transition and lanthanide metals with specific ligand fields afford single-ion anisotropies providing an easy-axis for the magnetization. In this regard, the new trigonally capped titanium (III) precursor, [Et4N][Tp*Ti(CN)3] (Tp* = tris(3,5-dimethylpyrazolyl)borohydride), was prepared. Concomitant hydrolysis, oxidation, and coordination of this titanium precursor affords a family of trinuclear carboxylate compounds, {(Tp*TiIV)(?2-OAc)2(?2-O)M(?2-O)(?2-OAc)2(TiIVTp*)} (M = CrIII, MnII, CoII), with interesting magnetic properties. The use of the equatorially coordinating bis(trimethylsilyl)amide ligand, [N(SiMe3)2]-, enforces a trigonal pyramidal framework for the stabilization of prolate lanthanide SMMs. The compounds, [Li(THF)4]{LnIII[N(SiMe3)2]3Cl} (Ln = Er, Tm), exhibit single-molecule magnet behavior with the erbium analog showing magnetic hysteresis up to 3 K.
