Room-Temperature Spin-Mediated Coupling in Hybrid Magnetic, Organic, and Oxide Structures and Devices
Abstract
During the full period of this project we have (1) demonstrated room-temperature effects of the remanent magnetization from electrically-isolated magnetic films on the conductivity and electroluminescence of organic devices, (2) developed and applied a percolation theory of magnetoresistance to describe magnetic field effects on spin transport in organic semiconductors, (3) discovered and theoretically explained the effects of traps and unpaired spins on room-temperature magnetoresistance, (4) developed a theory for spin diffusion in hopping transport due to hyperfine interaction and spin-orbit interaction, (5) predicted and measured spatial interference patterns from multiple coherent spin torque oscillators, (6) predicted spin-wave dispersion relations in magnonic crystals, (7) predicted electric-field control of spin-wave propagation velocities and interferometers, (8) developed a theory for spin lifetimes and spin Hall conductivities for oxide two-dimensionalelectron gases, (9) measured spin-orbit interactions in nanoscale wires in oxide semiconductor interfaces, (10) demonstrated electrical control of ferromagnetism in the LAO/STO system, (11) demonstrated hybrid organic/inorganic spin valves, (12) developed interfacial magnetic systems based on oxide superlattices, and (13) demonstrated GHz operation of sketched oxide transistors at the LAO/STO interface.
