Book Synopsis Ab initio study of CPP transport in Fe/Cr/Fe trilayers: influence of transition metal impurities by : Heike C. Herper
Download or read book Ab initio study of CPP transport in Fe/Cr/Fe trilayers: influence of transition metal impurities written by Heike C. Herper and published by . This book was released on 2003 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: The transport properties of Fe(001)/Cr/Fe(001) trilayers are discussed with respect to the influence of transition metal impurities in form of layers. We are able to show that the periodicity of the giant magnetoresistance is directly influenced by the interlayer exchange coupling (IEC). Furthermore, it is observed that the behavior of the IEC strongly depends on whether an impurity overlayer of Mn or V is used. It turns out that the size of the GMR is only little effected by 3d-transition metal impurities, which is in agreement with the experimental findings. The electronic and magnetic properties of the trilayers have been investigated within the fully relativistic, spin-polarized SKKR method and the LDA. The transport properties of the Fe/Cr/Fe systems have been derived from the fully relativistic spin-polarized Kubo-Greenwood equation.

Book excerpt: Utilizing the oscillatory interlayer exchange coupling in Fe/Cr superlattices, we have constructed ''double superlattice'' structures where a ferromagnetic (F) and an antiferromagnetic (AF) Fe/Cr superlattice are coupled through a Cr spacer. The minor hysteresis loops in the magnetization are shifted from zero field, i.e., the F superlattice is exchange biased by the AF one. The double superlattices are sputter-deposited with (211) epitaxy and possess uniaxial in-plane magnetic anisotropy. The magnitude of the bias field is satisfactorily described by the classic formula for collinear spin structures. The coherent structure and insensitivity to atomic-scale roughness makes it possible to determine the spin distribution by polarized neutron reflectivity, which confirms that the spin structure is collinear. The magnetic reversal behavior of the double superlattices suggests that a realistic model of exchange bias needs to address the process of nucleating local reverse domains.

Book Synopsis Interface and Topology in Magnetism by : Ali Sucipto Tan
Download or read book Interface and Topology in Magnetism written by Ali Sucipto Tan and published by . This book was released on 2016 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation explores interface interactions, topology of spin structures, and the use of interface interactions in manipulating the topology of spin structures. First, I will present our work on interface interactions in magnetic thin film heterostructures. A majority of interesting phenomena in magnetic heterostructures are caused primarily by the interface interactions. In exchange bias system CoO/MgO/Fe/Ag(001), the role of frozen and rotatable antiferromagnetic spins in exchange bias system was investigated using X-ray Magnetic Linear Dichroism (XMLD). In the Py/FeMn/Ni/Cu(001) system, the indirect coupling through an antiferromagnetic spacer layer was studied through anisotropy measurements using Rotating-Field Magneto-Optical Kerr Effect (ROTMOKE). Second, I will present our work on artificial topological spin structures. Traditionally, research on nanostructured magnetic materials has focused on the study of uniformly magnetized thin films. With the increasing capability to prepare and manipulate non-uniform spin configurations in recent years, various topological spin structure have been realized. In magnetic thin films, magnetic vortex states can be stabilized by reducing the lateral dimension of the magnetic thin film to the nanoscale due to the increased shape anisotropy. By combining this shape anisotropy and interlayer exchange coupling at the interface, we showed that more complex topological spin structures such as spin skyrmions and hedgehog spin merons can be stabilized and manipulated. By utilizing uniaxial strain in a ferroelectric-ferromagnetic system Co/Cu/PMN-PT(011), we demonstrated a method to manipulate the circulation of a magnetic vortex state using strain.

This book was released on 2010-04-16 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: This first focused treatment on a hot topic highlights fundamental aspects as well as technological applications arising from a fascinating area of condensed matter physics. The editors have excellent track records and, in light of the broadness of the topic, retain the focus on antiferromagnetic oxides. They thus cover such topics as dichroism in x-ray absorption, non-magnetic substrates, exchange bias, ferromagnetic-antiferromagnetic interface coupling and oxide multilayers, as well as imaging using soft x-ray microscopy.

Book excerpt: Carbon Based Magnetism is the most complete, detailed, and accurate guide on the magnetism of carbon, the main element of living creatures. Written by the leading experts in the field, the book provides a comprehensive review of relevant experimental data and theoretical concepts related to the magnetism of metal-free carbon systems. These systems include carbon based compounds, namely organic radical magnetic systems, and magnetic materials based on carbon structures. The aim is to advance the understanding of the fundamental properties of carbon. This volume discusses all major modern hypotheses on the physical nature of magnetic ordering in carbon systems. The first chapters deal with magnetic ordering mechanisms in p-electron systems as well as molecular magnets with spins residing only in p-orbitals. The following chapters explore the magnetic properties of pure carbon, with particular emphasis on nanosized carbon systems with closed boundary (fullerenes and nanotubes) and with open boundary (structures with edge-localized magnetic states). The remaining chapters focus on newer topics: experimental observation and theoretical models for magnetic ordering above room temperature in pure carbon. The book also includes twenty three review articles that summarize the most significant recent and ongoing exciting scientific developments and provide the explanation. It also highlights some problems that have yet to be solved and points out new avenues for research. This book will appeal to physicists, chemists and biologists.
