▼ This thesis contains several investigations of magnetoelectric effects and ferroelectricity in complex oxides studied via first-principles calculations. We start by reviewing the mechanisms of ferroelectricity and magnetoelectric e ffects, and then we give a brief introduction to the first-principles computational methods that are involved. Next, our investigations are divided into two parts. The first half focuses on the magnetoelectric effects, while the second half is mainly on ferroelectricity. The first half aims to examine the lattice contribution to the magnetoelectricity by investigating the dynamical magnetic charge tensors induced by different mechanisms. Through the study of Cr2O3 and a fictitious material KITPite, we find that the dynamical magnetic charges driven by exchange striction are more significant than the ones induced by spin-orbit coupling. Since the lattice contribution to the magnetoelectric effect is proportional to the dynamical magnetic charges, we also study the magnetic charges and the magnetoelectric coupling in hexagonal manganite RMnO3 and ferrite RFeO3. Our results further confirm the importance of the exchange-striction mechanism in inducing large magnetic charges, but we also notice that the magnetoelectric contributions from various phonons tend to cancel each other, leading to a great reduction of the total coupling. These investigations not only provide a prediction of the magnetoelectric coupling constant in RMnO3 and RFeO3, but also emphasize the importance of phonons in magnetoelectric coupling. In the second half of the thesis, we focus on predicting new ferroelectrics in the family of corundum derivatives. Many new corundum derivatives have been synthesized recently; these are automatically polar, and many are magnetic as well. However, a polar material is only called ferroelectric if the polarization is reversible by an external field, and it is not yet clear whether or not this is the case for these new materials. Motivated by this question, we use a structural constraint method to study the ferroelectric reversal path and energy barrier of several corundum derivatives. As a result, we predict several FE candidates with insulting reversal paths and low barrier energies. Since the hysteresis behavior of ferroelectrics is attributed to the ferroelectric domain wall motion, we further investigate the formation and motion of ferroelectric domain walls in corundum derivatives. Our study predicts the atomic structure and orientation of the ferroelectric domain wall, as well as the shape of ferroelectric domains. In addition, we fi nd novel properties at domain walls, including a strong magnetoelectric coupling and an interlocking between chirality and polarization. Moreover, we use the structural constraint method to study the barrier energy of ferroelectric domain wall reversal. Our results suggest that the barrier energy is linearly correlated with the bond valence sum, which can be used as a guide to find new ferroelectrics in the… Advisors/Committee Members: Vanderbilt, David (chair), Hinch, Jane (internal member), Chandra, Premala (internal member), Keeton, Charles R (internal member), Dabo, Ismaila (outside member).

This thesis covers the study of multiferroics and magnetoelectrics by utilizing a collection of scanning force microscopy to investigate the cross-coupled phenomena. We mainly focus on the multiferroic hexagonal REMnO₃ (RE = rare earth), an improper ferroelectrics with the coexistence of ferroelectricity (T_extrm{C} = 1200 - 1500 K) and antiferromagnetism (T_extrm{N} = 70 - 120 K), and explore in depth the magnetoelectric effect of this system microscopically. Using cryogenic magnetic force microscope (MFM), we observed uncompensated magnetic moment along antiferromagnetic domain walls, which coincides with the ferroelectric domain boundaries. This magnetism presents an alternating feature around the multiferroic vortex, and correlates with each other through the vortex network. The study of the magnetic field dependence of domain wall magnetism also provides a way to probe the intrinsic bulk domain state. To directly image the magnetoelectric domains, we developed a novel mesoscopic technique, namely, magnetoelectric force microscopy (MeFM), to probe the local electric field-induced magnetization based on MFM. The detail of the novel technique will be presented in Chapter 2. With the application of MeFM in hexagonal manganities, we observed that the magnetoelectric response changes sign at each structural domain wall, which provides compelling evidence for a lattice-mediated magnetoelectric coupling. More interestingly, the magnetoelectric effect diverges when approaching the tri-critical point in T-H phase diagram, where critical fluctuation plays a crucial role. Our study suggests the phase competition as a possibility to enhance magnetoelectric coupling. The systematic study of hexagonal manganites, including ErMnO₃ and YbMnO₃, disentangles the contribution from Mn and rare earth sublattices, suggesting that the 3d-4f coupling and the Ising anisotropy of rare earth spins are the key ingredients to understand the re-entrant spin-reorientation phase boundary and the emergence of a tri-critical point.

▼ The Landau Fermi liquid theory is a very successful theory in condensed matter physics. It provides a phenomenological framework for describing thermodynamics, transport and collective modes of itinerant fermionic systems. In 1957, Silin described the spin waves in polarized Fermi liquids based on Landau Fermi liquid theory, which are related to series of components of the spherical harmonic expansion of the fermi surface. It has been proved by Pomeranchuck that for the Fermi surface to be stable, the Landau parameters should satisfy the relation: F_l^s,a>-(2l+1). Whenever the relation is violated, there will exist an instability of the Fermi surface known as a Pomeranchuck instability, such as the Stoner ferromagnetism when F₀^a→ -1⁺, or phase separation when F₀^s→ -1⁺. In 1959, Abrikosov and Dzyaloshinskii developed a ferromagnetic Fermi liquid theory(FFLT) of itinerant ferromagnetism based on Landau Fermi liquid theory, whose microscopic foundations were established later by Dzyaloshiskii and Kondratenko. Further studies had been made of this state using a generalized Pomeranchuck instability based on the FFLT of Blagoev, Engelbrecht and Bedell and Bedell and Blagoev. In this thesis, I study a magnetically ordered system with spin orbit magnetism, where the order parameter has a net spin current and no net magnetization in both two dimension and three dimension. Starting from a Fermi liquid theory, similar to that for a weak ferromagnet, I have shown that this excitation emerges from an exotic magnetic Fermi liquid state that is protected by a generalized Pomeranchuck condition. I derive the propagating mode using the Landau kinetic equation, and find that the dispersion of the mode has a sqrt q behavior in leading order in 2D. I also find an instability toward superconductivity induced by this exotic mode, and a further analysis based on the forward scattering sum rule strongly suggests that this superconductivity has triplet pairing symmetry. I perform similar studies in the 3D case, with a slightly different magnetic system and find that the mode leads to a Lifshitz-like instability most likely toward an inhomogeneous magnetic state in one of the phases. I also study the collective modes in itinerant ferromagnetic system, which is related to the F₀^a pomeranchuck instability. Using FFLT, I obtained the well-known magnon (Nambu-Goldstone) mode and a gapped mode that was first found by Bedell and Blagoev. I have identified this mode as the Higgs boson (amplitude mode) of a ferromagnetic metal. This is identified as the Higgs since it can be shown that it corresponds to a fluctuation of the amplitude of the order parameter. I use this model to describe the itinerant-electron ferromagnetic material MnSi. By fitting the model with the existing experimental results, I calculate the dynamical structure function and see well-defined peaks contributed from the magnon and the Higgs. From my estimates of the relative intensity of the Higgs amplitude mode I expect that it can be seen in neutron scattering… Advisors/Committee Members: Kevin S. Bedell (Thesis advisor).

▼ Data storage technologies that utilize magnetic materials for storage are key for both increasing areal density of storage in traditional hard disk media and providing low energy alternatives to traditional CMOS technology through spintronic memory and logic devices. Spintronic memory relies on the spin of an electron rather than charge and is a promising candidate for achieving non-volatility which can provide dramatic energy savings. A key challenge for magnetic based storage is achieving 10 nm or smaller feature sizes while retaining thermal stability. This requires development of magnetic thin films with large magnetocrystalline anisotropy. Switching the magnetization of high anisotropy magnetic materials requires large Oersted field or spin current. One way to decrease the switching energy is to lower the anisotropy during the switching process with an applied strain or heat. This scheme retains thermal stability during storage and makes write energies feasible from a technological aspect. Development of suitable high anisotropy materials at sub 10 nm scale has proved difficult due to limitations on traditional thin film growth methods, nanoscale effects, and additional requirements on materials for memory applications. The effect of a static strain on the magnetic anisotropy is well understood, but less so for application in devices which require fast switching and high cycling. The other approach to lowering switching energies is to use magnetic materials with small magnetization, such as Mn-based compounds. I will discuss my experiments to advance understanding of: development of FePt for HAMR media, effect of strain assisted switching on the spin state of FePt, and development of novel high anisotropy Mn-based materials with low magnetization. Finally, I will present my experimental realization of Ru as the 4th room temperature ferromagnetic element. Ru has been predicted to become ferromagnetic when placed into a metastable tetragonal or cubic phase. This new phase of Ru also has potential to achieve the requirements for a viable spintronic device. I will show my work on the realization of the tetragonal phase Ru using seed layer engineering in thin films, and its associated ferromagnetic properties.

▼ We present studies of the electical detection of spin injection and transport in InSb/CoFe heterostructures. As a narrow gap semiconductor, InSb has a high mobility and strong spin-orbit interaction. Using ferromagnetic CoFe, lateral InSb/CoFe devices are fabricated by semiconductor processing techniques. The saturation magnetizations of various CoFe electrodes with different widths are calculated from Hall measurements in which the fringing fields of the CoFe electrodes are detected. A magnetic model provides reasonable estimation of the saturation magnetization for micrometer scale geometries. The interface magnetoresistance measurements of InSb/CoFe thin film layered structures present a unique peak at low field, having a symmetric behavior in magnetic field with a critical field Hc and a strong temperature dependence. We attribute our signal to a ferromagnetic phase in the InSb induced by spin injection. In a non-local lateral spin valve measurement, we observed the following. Firstly, Hc of the lateral spin valve signals is identical to Hc of interface magnetoresistance signals. Secondly, the non-local lateral spin valve signals are strongly dependent on temperature, which is also a unique characteristic magnetoresistance. Thirdly, the signals are tunable in response to an applied injector bias. Lastly, the signals are dependent on the exact interfaces. Based on these observations, the detected signals may be considered as spin current signals. The Hall and magnetoresistance signals are measured locally and non-locally in InSb/CoFe Hall devices. The non-local magnetoresistance signals exhibit asymmetric behavior in applied magnetic field which are considered as signatures of spin phenomena. The non-local Hall signals present switching behavior with the CoFe magnetization switching at the coercive field. The non-local Hall signals in a perpendicular field show Hc, similarly seen in non-local lateral spin valves. Inverse spin Hall effect measurements with tilted magnetic fields show an in-plane magnetic field dependence in non-local type Hall signal and a perpendicular magnetic field dependence in the local Hall measurement. We have found that the signal can have its origin in a spin current from our observation of Hc and hysteresis in the magnetization traces. As yet, the spin current transport mechanism is unknown.

▼ Esta tesis se centra en el estudio teórico de los magnones en el contexto de una red ferromagnética colineal en una y dos dimensiones. Este estudio se dedicó a dos modelos diferentes. El primer modelo busca comprender el comportamiento de los magnones en una monocapa de CrI₃. Mientras el segundo corresponde a un modelo de juguete unidimensional desarrollado para comprender el acoplamiento magnón-fonón que puede surgir debido a la existencia de un campo magnético que varía en el espacio. En el primer capítulo, se presentan los antecedentes matemáticos necesarios para comprender los dos modelos analizados en esta tesis. El tema más crucial cubierto en este capítulo es la transformación de Holstein-Primakoff y su aplicación en la red de espín más general que encapsula cada sistema discutido en esta tesis. En este capítulo, también se resumen los métodos numéricos utilizados para resolver las energías propias y los estados propios de los sistemas bosónicos. El segundo capítulo está dedicado al estudio de los magnones en una capa bidimensional de CrI₃. La descripción teórica de este sistema se realiza a través del modelo de Heisenberg-Kitaev, que se propuso recientemente como la teoría subyacente que describe su fenomenología. En este trabajo, se demuestra constructivamente que los magnones tienen una topología no trivial, y se realiza una predicción teórica del efecto Hall térmico, donde se muestra que el signo de la conductividad térmica de Hall depende de la temperatura del sistema. En el último capítulo, se estudia la interacción entre magnones y fonones. La característica esencial de la teoría detrás de este capítulo es que la forma de un campo magnético, que varía en el espacio podría controlar el acoplamiento entre magnones y fonones. En este capítulo, se utilizan los datos conocidos del YIG para mostrar qué gradiente de campo magnético se necesita para obtener resultados comparables a los observados naturalmente en el mismo material debido al acoplamiento descrito fenomenológicamente por Kittel.

Thesis Ph. D. Michigan State University. Physics 2015

When a conventional superconductor (S) is placed in contact with a ferromagnet (F), the decay length of the pair correlations in the ferromagnet is very short, on the order of a nm in a strong ferromagnet such as Co or Fe. This is due to the spin-polarized nature of the ferromagnet, whereas the spins of Cooper pairs in a conventional superconductor are anti-aligned in a spin-singlet state. However, in 2001, theorists predicted that long-range pair correlations in a spin-triplet state could be generated through magnetic inhomogeneity. With parallel spins, the decay length of these correlations extends in principle to that of a superconductor-normal metal system, which can be on the order of a micron at sufficiently low temperature.This effect has been observed experimentally by several groups, commonly through the use of extrinsic magnetic inhomogeneity in samples with multiple magnetic layers. Josephson junction measurements have demonstrated critical currents orders of magnitude larger in samples with this inhomogeneity compared to samples without. However, the ability to reliably control the spin-state of the pair correlations in a single sample has yet to be realized.The goal of this work is to perform measurements on Josephson junctions in which the inhomogeneity can be manipulated. Our approach is to fabricate S/F'/F/F"/S Josephson junctions where we can control the relative magnetization orientations of all three ferromagnetic layers. In order to realize this control, we first had to perform studies to characterize various magnetic materials, most notably a NiFe alloy similar to Permalloy and Co/Ru/Co, a synthetic antiferromagnet. Studies of the NiFe have demonstrated its ability to be used as a spin-triplet generator. Measurements have also been taken of NiFe films to determine how easily its magnetization direction can be rotated in an external field. We have also measured the magnetic hardness of Co/Ru/Co synthetic antiferromagnets as a function of the Co thickness. By keeping the Co thin, we can minimize the rotation of this layer under the influence of small applied magnetic fields.Using these results, we demonstrate amplitude modulation of the supercurrent in S/F'/F/F"/S Josephson junctions which is dependent on the magnetization direction of NiFe. Through the use of an external field, the magnetization of the NiFe F" layer can be rotated with respect to the magnetization of the Co/Ru/Co F layer. By rotating into and out of a non-collinear state, we have demonstrated the ability to tune the supercurrent from a spin-triplet to a spin-singlet state, effectively turning the supercurrent in these junctions "on" and "off."

▼ In hybrid mesoscopic systems the Meissner response of a superconducting film can be very different from its bulk behaviour. For instance, in normal (N) superconductor (S) bilayers screening can be greatly enhanced depending on the relative material properties and interface conditions. Furthermore, with the addition of ferromagnetic (F) layers comes the possibility of generating a paramagnetic screening response due to spin triplet pairs. Such pairs are produced from the mixing of opposing microscopic orders within S (which conventionally hosts electron pairs of opposite spin and momenta) and F (inside which spin symmetry is broken). The net result is a conversion of a fraction of the pairs to an odd-frequency s-wave triplet state. Any resultant modifications to the screening manifest in the flux profile across a sample which is directly probed using low energy muon spin rotation (LEμSR). Results of LEμSR experiments involving layered systems comprised of N, S and F elements are presented within chapter 3. A discrepancy between the pre-existing quasiclassical theory and measured flux profiles in the presence of an F layer was observed. A large enhancement to the flux lowering which could not be interpreted within the traditional S/F proximity picture was found. New theoretical developments have since suggested that coupled to direct electronic proximity effects within these systems is an additional electromagnetic component. Chapter 4 presents the results of analysing LEμSR data using a spatial flux profile consistent with new theory. In doing so, the observed anomalous enhancement could be successfully reconciled with the electromagnetic proximity effect. Subsequent experimental work in chapters 4 - 6 sought to test the main predictions of the theory by manipulating S/F interfaces within a variety of different structures. In all tested cases the theory provided an excellent description of experiment suggesting the importance of considering electromagnetic effects within S/F hybrid systems.

The objective of this work is to employ spin-polarized density functional theory (SDFT) calculations for the exploration of ultrathin magnetic lms with large magnetic moments and a strong perpendicular anisotropy. Ultrathin monolayer lms of Fe1..xCox (with x = 0, 0:25, 0:5, 0:75 and 1) on Rh(001) were addressed to study their magnetic properties using the all-electron full-potential linearized augmented plane wave (FLAPW) method in lm geometry. We studied the magnetic order of these lms including relaxations of the topmost layers. Fe1..xCox monolayer lms were found to be ferromagnetic (FM) in a broad range of Co content x with a maximum magnetic moment of 2:8 B and of an out-of-plane magnetocrystalline anisotropy of 0:25 meV per magnetic atom at x = 0:5. The SDFT results were mapped onto a classical Heisenberg model, demonstrating FM Fe-Co and Co-Co coupling, while the Fe-Fe interaction is antiferromagnetic (AFM) on Rh(001). The ordering temperature was estimated to be well above room temperature (482 K). Using SDFT calculations, we have studied the magnetic states including collinear and noncollinear magnetic coupling in Fe1..xCox ultrathin lms on Rh(001) substrate. We found for 7 layes of Rh spacer an interlayer exchange coupling (IEC) with absolute values of 3:4 and 2:9 meV per 3d atom corresponding to the two magnetic lms Co/Rh/Co and FeCo/Rh/Co, respectively. These lms show a very large IEC compared to that obtained for Fe/Ag/Fe or Fe/Au/Fe lms, which is IEC is one order of magnitude smaller. We found also that the IEC oscillates with increasing Rh spacer thickness, i.e. the Rh spacers mediate an interlayer coupling which couples the magnetizations either ferromagnetically or antiferromagnetically depending on the spacer thickness. Our calculations give an antiferromagnetic (AFM) coupling for 5 layers of Rh spacer and a ferromagnetic (FM) one for 7 layers, as has been experimentally detected for thicker magnetic lms. The exchange coupling energy including spin orbit coupling was calculated for the nFeCo/5Rh/Co lms in the framework of of the constrained SDFT. A strong perpendicular anisotropy of 0:15 meV per 3d atom has been found for the 2FeCo/5Rh/Co lm while the single FeCo monolayer system FeCo/5Rh/Co preferred an in-plane magnetic anisotropy. This result suggests that the competition between IEC and magnetic anisotropy of coupled lms may result in noncollinear ordering. The results of the constrained SDFT are mapped onto the bilinear-biquadratic exchange coupling model of the Hamiltonian including the uniaxial anisotropy term. We found a values of 3:55 and 0:62 meV per 3d atom for the bilinear and biquadratic coupling constants respectively Fonctionnelles densité Density functionals

▼ A hundred years passed since the discovery of superconductivity, but it is only during last decades superconductors transformed from exotic object for physical experiments to practically promising materials. During this time new theoretical concepts, measurement techniques and fabrication methods were invented in order to study these materials. New types of superconductors were discovered. It is hard to overestimate current impact of superconductivity in modern life: the most sensitive devices (SQUIDs) based on Josephson effect, loss-free cables for electric networks in Tokyo and New York, high-speed levitating trains in China and Japan, high-field magnets for magneto-resonance imaging and power generators, and other applications have become available. One of the most popular and well studied superconducting material is a YBa₂Cu₃O₇ (YBCO) high-temperature superconductor (HTSC). High working temperatures, high transport currents and technological effectiveness enable a potential of YBCO application in all possible areas from industrial power applications to microelectronics. Hence, a technological control or enhancement of YBCO performance is of current importance. Moreover, well studied YBCO is a good model material to study some physical aspects of HTSC behaviour which are not answered or not quantified. Enhancement of superconducting properties or even novel physical effects can be obtained combining superconducting and ferromagnetic materials (so-called hybrids). FePt ferromagnetic material is of a particular interest for application in highfield hybrids because of high coercive force and magnetic anisotropy. In addition FePt is promising for “traditional” applications of ferromagnets, such as magnetic recording media, micro-electro mechanical systems or high energy product magnets. However, high degree of technological control is required in order to reach necessary performance of FePt. Functional materials, such as YBCO or FePt, demonstrate their best performance or reveal certain physical effects in form of thin films. In this work large degree of control on structure of quasi-single crystal superconducting YBCO thin films and hard ferromagnetic L1₀-FePt thin films is demonstrated simply by varying laser frequency of pulsed laser deposition. Significant structural modifications have been obtained for the films of constant thicknesses. These modifications are shown to dramatically affect corresponding physical properties of thin films.
