Since the first usage of magnets as navigation tools, magnetism has been an integral part of human technology. As such, with increased demand for more sophisticated technologies, the need to understand magnetism and its applications has also increased. In modern times, the focus of new technologies is on scalability, or how things behave on the smallest scales. To this end it is necessary to understand the fundamental and practical behaviors of magnetic materials at this limit. Recent discoveries in the field of true 2D magnets and the field of topological matter demands investigation of the intersection between these two fields. In the first part of this work a theoretical analysis of the topological behavior of magnon bands in CrI3-like magnetic heterostructures is carried out. This analysis revealed a rich topological phase space wherein topological phase boundaries correspond to abrupt jumps in the thermal Hall conductance of the system, reminiscent of the quantum anomalous Hall effect. Additionally these systems showed distinct and repeating features between heterostructures with an even number of layers and those with an odd number of layers, making it theoretically possible to distinguish between the two based on the behavior of the thermal Hall conductance. Additional work was done on applications of magnetic thin film toward the field of spintronics. Spin-based magnetic random-access memory (MRAM) has a particular advantage over current electronic technology in its intrinsic non-volatility. Additionally, current MRAM devices that use spin-transfer torque can be improved by finding materials with high intrinsic perpendicular magnetic anisotropy which do not rely on interfacial-perpendicular anisotropy. To this end an investigation of the substrate dependent crystallinity of the Heusler alloy Fe2MnSn was performed using in-plane x-ray diffraction. By studying how the growth and orientation of the Bragg peaks ((200) and (002)) that correspond to the primary crystal axes, (a-b axes and c axis, respectively) it was determined that lattice matching and substrate play a large role in the formation of crystal plane orientations, potentially shining light on how these growth modes can influence the magnetic anisotropy of the films.

The magnetic proximity effect (MPE) has generated a lot of interest recently due to its ability to introduce magnetic order into otherwise non-magnetic systems. It can be realized in 2D material stacks as well as inside 3D material thin film heterostructure. The work in this thesis explores MPE inside a variety of heterostructures using multiple measurement techniques. It demonstrates the first realization of MPE inside a thin film of Pt from a ferrimagnetic insulator CoFe2O4. Next, it experimentally demonstrates a novel growth method for synthesizing high quality thin films of topological Dirac semimetal Na3Bi on Al2O3 substrate, and further extends this growth method to synthesize the first topological Dirac semimetal/magnetic insulator heterostructure of Na3Bi/CoFe2O4. Finally, it lays the groundwork for ambitious studies of MPE inside 2D material/magnetic insulator heterostructures using angle-resolved photoemission spectroscopy. This is accomplished by a new process of transferring flakes of 2D materials on top of freshly deposited thin films while inside an ultra-high vacuum environment.

This book provides a comprehensive overview of the latest developments in the field of spin dynamics and magnetic damping. It discusses the various ways to tune damping, specifically, dynamic and static control in a ferromagnetic layer/heavy metal layer. In addition, it addresses all optical detection techniques for the investigation of modulation of damping, for example, the time-resolved magneto-optical Kerr effect technique.

A low-dimensional magnet is a key to the next generation of electronic devices. In some respects, low-dimensional magnets refer to nanomagnets (nanostructured magnets) or single-molecule magnets (molecular nanomagnets). They also include the group of magnetic nanoparticles, which have been widely used in biomedicine, technology, industries, and environmental remediation. Low-dimensional magnetic materials can be used effectively in the future in powerful computers (hard drives, magnetic random-access memory, ultra-low power consumption switches, etc.). The properties of these materials largely depend on the doping level, phase, defects, and morphology. This book covers various nanomagnets and magnetic materials. The basic concepts, various synthetic approaches, characterizations, and mathematical understanding of nanomaterials are provided. Some fundamental applications of 1D, 2D, and 3D materials are covered. This book provides the fundamentals of low-dimensional magnets along with synthesis, theories, structure-property relations, and applications of ferromagnetic nanomaterials. This book broadens our fundamental understanding of ferromagnetism and mechanisms for realization and advancement in devices with improved energy efficiency and high storage capacity.

In a new branch of physics and technology, called spin-electronics or spintronics, the flow of electrical charge (usual current) as well as the flow of electron spin, the so-called "spin current", are manipulated and controlled together. This book is intended to provide an introduction and guide to the new physics and applications of spin current.

The present book is the second edition of Amikam Aharoni's Introduction to the Theory of Ferromagnetism, based on a popular lecture course. Like its predecessor, it serves a two-fold purpose: First, it is a textbook for first-year graduate and advanced undergraduate students in both physics and engineering. Second, it explains the basic theoretical principles on which the work is based for practising engineers and experimental physicists who work in the field of magnetism, thus also serving to a certain extent as a reference book. For both professionals and students the emphasis is on introducing the foundations of the different subfields, highlighting the direction and tendency of the most recent research. For this new edition, the author has thoroughly updated the material especially of chapters 9 ('The Nucleation Problem') and 11 ('Numerical Micromagnetics'), which now contain the state of the art required by students and professionals who work on advanced topics of ferromagnetism. From reviews on the 1/e: '... a much needed, thorough introduction and guide to the literature. It is full of wisdom and commentary. Even more, it is Amikam Aharoni at his best - telling a story... He is fun to read... The extensive references provide an advanced review of micromagnetics and supply sources for suitable exercises... there is much for the student to do with the guidance provided by Introduction to the Theory of Ferromagnetism.'

This book presents both experimental and theoretical aspects of topology in magnetism. It first discusses how the topology in real space is relevant for a variety of magnetic spin structures, including domain walls, vortices, skyrmions, and dynamic excitations, and then focuses on the phenomena that are driven by distinct topology in reciprocal momentum space, such as anomalous and spin Hall effects, topological insulators, and Weyl semimetals. Lastly, it examines how topology influences dynamic phenomena and excitations (such as spin waves, magnons, localized dynamic solitons, and Majorana fermions). The book also shows how these developments promise to lead the transformative revolution of information technology.
