点击翻译按钮获取中文摘要

This theoretical project explores the fundamental physics of electronic, magnetic andTransport properties of nanoscale magnetic junctions. The major emphasis is on spin-Polarized electronic transport in the nanojunctions, in which a small amount of variousMetallic, semiconducting or insulating materials is placed as a contact between twoFerromagnetic nanowires. First-principles density functional calculations will bePerformed to predict electronic, magnetic and transport chacteristics of theseNanojunctions. Micromagnetic modeling will be used to understand the magneticStructure of nanocontacts and tight-binding models will be developed to tread disorderedSystems and to explore the influence of localized states on magnetotransport in magneticTunnel junctions. These theoretical studies will guide experimental investigations of the Nanoscale junction fabricated by state-of-the-art nanofabrication techniques and willComplement the established experimental program at Nebraska. The research willFacilitate the development of novel magnetoelectronic devices, which merge spin degreesOf freedom into electronic nanotechnologies.%%%This theoretical project explores the fundamental physics of electronic, magnetic and Transport properties of nanoscale magnetic junctions.
