First-principles calculation of spin transport and relaxation in magnetic heterostructures (Conference Presentation)

Paper Abstract

Manipulation of a spin current at nanoscale is desired in many proposed spintronics devices. Magnetic multilayers consisting of ferromagnetic, ferrimagnetic and nonmagetic materials show rich phenomena when a spin current propagates through the multilayers. An interface of ferromagnetic and nonmagnetic metals has been demonstrated to play an important role in the generation and dissipation of a spin current. Using first-principles scattering calculation, we study the transport and relaxation of spin currents in typical transition metals and alloys and their interfaces. In particular, we focus on identifying the correlation of spin transport and relaxation with the specific order parameters of magnetic materials. By examining the spin-Hall conductivity and spin-flip diffusion length as a function of conductivity (resistivity), we are able to distinguish different dominant physical mechanisms of the generation and dissipation of spin currents.
