Available in PDF, EPUB and Kindle. Book excerpt: Spintronics, based on the use of the spin degree of freedom of electrons, has attracted much attention as an avenue for creating energy-efficient memory storage and electronic devices. A pure spin current, where spin angular momentum is transferred without any charge current, is desirable to realize low-loss devices due to the lack of heat dissipation associated with moving charge. Low-damping magnetic insulator thin films that can propagate spin currents with minimal dissipation are essential for this purpose. At the same time, magnetic insulators are also useful to stabilize novel ground states in neighboring materials. We have identified a class of spinel ferrite magnetic insulators which have desirable properties for these applications. I will present results on spin-to-charge and charge-to-spin conversion in low-damping MgAl0.5Fe1.5O4 (MAFO) and Li0.5Al1Fe1.5O4 (LAFO) thin films, which show ideal properties for pure spin current applications. Further, I will discuss MAFO/Bi2Se3 bilayers in the context of inducing a magnetic proximity effect in a topological insulator, and I will show that common techniques currently used to detect magnetic proximity effects are insufficient. Finally, I will characterize LaTiO3 thin films for charge-to-spin conversion in bilayers with CoFeB. These results highlight both the promise and challenges associated with building magnetic heterostructures for novel, energy-efficient devices.

Book excerpt: In the past several decades, the research on spin transport and magnetism has led to remarkable scientific and technological breakthroughs, including Albert Fert and Peter Grünberg’s Nobel Prize-winning discovery of giant magnetoresistance (GMR) in magnetic metallic multilayers. Handbook of Spin Transport and Magnetism provides a comprehensive, balanced account of the state of the art in the field known as spin electronics or spintronics. It reveals how key phenomena first discovered in one class of materials, such as spin injection in metals, have been revisited decades later in other materials systems, including silicon, organic semiconductors, carbon nanotubes, graphene, and carefully engineered nanostructures. The first section of the book offers a historical and personal perspective of the field written by Nobel Prize laureate Albert Fert. The second section addresses physical phenomena, such as GMR, in hybrid structures of ferromagnetic and normal metals. The third section discusses recent developments in spin-dependent tunneling, including magnetic tunnel junctions with ferroelectric barriers. In the fourth section, the contributors look at how to control spin and magnetism in semiconductors. In the fifth section, they examine phenomena typically found in nanostructures made from metals, superconductors, molecular magnets, carbon nanotubes, quantum dots, and graphene. The final section covers novel spin-based applications, including advanced magnetic sensors, nonvolatile magnetoresistive random access memory, and semiconductor spin-lasers. The techniques and materials of spintronics have rapidly evolved in recent years, leading to vast improvements in hard drive storage and magnetic sensing. With extensive cross-references between chapters, this seminal handbook provides a complete guide to spin transport and magnetism across various classes of materials and structures.

Available in PDF, EPUB and Kindle. Book excerpt: The rise of neuromorphic computing and iteration of new memory call for energy-efficient magnetization manipulation by spin and a better understanding of fundamental magnetotransport properties. Over the past decades, most works on the spin source focused on polycrystalline and amorphous materials. In the first part of this dissertation, we investigate the spin Hall effect in epitaxial Pt (200), (220), and (111). A tunable spin current generation can be achieved in Pt (220). The charge-to-spin conversion efficiency can be significantly enhanced along specific crystallographic orientation by utilizing the anisotropic resistivity Our work highlights the future work on enhanced SHE arising from crystalline orientation dependence which will boost the energy-efficient spintronic devices. On the other hand, tunable charge-to-spin conversion can be achieved by utilizing the materials with magnetic phase transition, which motivated us to study the 3d transition metal-Pt3 alloy and the rare earth material (Ho). Prior to further spintronics study, the fundamental magnetotransport properties in those materials need to be investigated. We successfully fabricate the chemically ordered epitaxial CrPt3 and FePt3. The large anomalous Hall effect measured on CrPt3 is in good agreement with the theoretical prediction. Moreover, by probing the exchange bias via electrical transport, it helps us quantitatively investigate the stability of antiferromagnetic nature in FePt3 under external perturbations. Furthermore, there are still intriguing properties remaining in "old" materials which lead to the magnetotransport study on hcp Ho and hcp Co. Our discovery of six-fold angular dependent magnetoresistance and step-like planar Hall effect in Ho gives rise to the strong magnetostriction coupled magnetoresistance. Remarkably, although predicted years ago, the strong c-axis dependent anomalous Hall conductivity in hcp Co lacks experimental support, which is demonstrated in this dissertation. The magnetotransport study on hcp Co offers a comprehensive picture of anisotropic anomalous Hall effect and magnetoresistance in ferromagnets with in-plane uniaxial magnetic anisotropy.

Available in PDF, EPUB and Kindle. Book excerpt: As we all know, electrons carry both charge and spin. The processing of information in conventional electronic devices is based only on the charge of electrons. Spin electronics, or spintronics, uses the spin of electrons, as well as their charge, to process information. Metals, semiconductors, and insulators are the basic materials that constitute the components of electronic devices, and these types of materials have been transforming all aspects of society for over a century. In contrast, magnetic metals, half-metals (including zero-gap half-metals), magnetic semiconductors (including spin-gapless semiconductors), dilute magnetic semiconductors, and magnetic insulators are the materials that will form the basis for spintronic devices. This book aims to collect a range of papers on novel materials that have intriguing physical properties and numerous potential practical applications in spintronics.

Available in PDF, EPUB and Kindle. Book excerpt: Dynamically controlling magnetism at the nanoscale is the foundation for realizing high-performance, low-power solid-state spintronic devices. The manipulation of nonuniform magnetization textures such as domain walls and skyrmions provide both a means to control magnetism in devices, and to gain new fundamental insights into spin-charge and spin-orbital interactions in magnetic materials. In this thesis, we examine novel mechanisms for the evolution and control of nonuniform magnetization textures. We first show that magnonic spin currents due to spin wave propagation can couple to and drive magnetic domain walls in nanowires mainly with experiments, supported by micromagnetic simulations. This work highlights a route towards integrating domain walls and spin waves for enhanced functionality in spintronics applications. We then focus on pure spin currents generated at the interface between a metallic ferromagnet and a heavy metal due to the spin Hall effect induced by strong spin orbit interaction. We demonstrate that the spin Hall effect can efficiently amplify or attenuate spin waves in an adjacent ferromagnet, and the efficiency of spin current generation can also be dramatically enhanced by optimizing the ferromagnet/heavy-metal interfaces. Moreover, we describe the microscopic mechanisms by which the spin Hall effect leads to magnetization switching, in the presence of chiral exchange interactions due to interfacial Dzyaloshinskii-Moriya interaction. This work shows the essential role that Dzyaloshinskii-Moriya interaction plays in magnetization switching. Finally, by harnessing this effect in carefully engineered materials, we show for the first time that the Dzyaloshinskii-Moriya interaction can stabilize topologically-protected skyrmions, whose statics and dynamics we have imaged for the first time in transition-metal ferromagnets at room temperature without any static external bias field. This finding provides not only experimental evidence of recent predictions but also opens the door to room-temperature skyrmion spintronics in robust thin-film heterostructures
Download or read book Spin Dynamics in Two Dimensional Quantum Materials written by Marc Vila Tusell and published by Springer Nature. This book was released on 2021-11-10 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis focuses on the exploration of nontrivial spin dynamics in graphene-based devices and topological materials, using realistic theoretical models and state-of-the-art quantum transport methodologies. The main outcomes of this work are: (i) the analysis of the crossover from diffusive to ballistic spin transport regimes in ultraclean graphene nonlocal devices, and (ii) investigation of spin transport and spin dynamics phenomena (such as the (quantum) spin Hall effect) in novel topological materials, such as monolayer Weyl semimetals WeTe2 and MoTe2. Indeed, the ballistic spin transport results are key for further interpretation of ultraclean spintronic devices, and will enable extracting precise values of spin diffusion lengths in diffusive transport and guide experiments in the (quasi)ballistic regime. Furthermore, the thesis provides an in-depth theoretical interpretation of puzzling huge measured efficiencies of the spin Hall effect in MoTe2, as well as a prediction of a novel canted quantum spin Hall effect in WTe2 with spins pointing in the yz plane.
