Spin Transport and Dynamics in Multilayer Magnetic Nanostructures

Spin Dependent Transport in Magnetic Nanostructures

Recent progress in physics on spin dependent transport in magnetic nanostructures is reviewed. Special attention is paid on the spin accumulation and spin current caused by spin injection into non-magnetic metals and semiconductors and superconductors. A variety of phenomena induced in nano-superconductor/ferromagnet devices are proposed, examining the spin-charge separation in superconductors.

Correlated Spin Transport in Nanostructures : Entanglement Creation and Spin Filtering

The ability to have nonlocal and pairwise entangled qubits is important for many quantum computing and quantum communication tasks. I review our proposals towards the realization of a solid state electron spin entangler, a device that creates a charge current carried by spin-entangled electrons which are nonlocal (EPR-pair) in space. An s-wave superconductor (SC) serves as the source of spin-en...

Spin-transfer torque in magnetic multilayer nanopillars

We consider a quasi one-dimensional configuration consisting of two small pieces of ferromagnetic material separated by a metallic one and contacted by two metallic leads. A spinpolarized current is injected from one lead. Our goal is to investigate the correlation induced between the magnetizations of the two ferromagnets by spin-transfer torque. This torque results from the interaction betwee...
