Abstract

We theoretically study the spin transport in a device consisting of a nonmagnetic metal (N) connected to ferromagnetic injector (F1) and detector (F2) electrodes. We solve the spin-dependent transport equations in a device with arbitrary interface resistance from a metallic-contact to tunneling regime, and obtain the conditions for efficient spin injection, accumulation, and transport in the device. In a spin-injection device containing a superconductor (F1/S/F2), we examine the effect of superconductivity on the spin transport. The spin-current induces the anomalous Hall effect in nonmagnetic conductors is also discussed.
