Spin Signals in Lateral Spin Valves with Double Nonmagnetic Bottom Electrodes

Journal of Magnetics, Volume 13, Number 3, 30 Sep 2008, Pages 81-84

Abstract

Spin injection and detection in lateral spin valves with double nonmagnetic bottom electrodes are investigated theoretically. Spin-polarized current injected from a magnetic electrode is split to two bottom electrodes, and nonlocal spin signals between the other magnetic electrode and the nonmagnetic electrodes are calculated from drift-diffusion equations. It is shown that the spin signal is approximately proportional to the associated current in the electrode.

Keywords: spin injection; spin detection; lateral spin valve; nonlocal spin signal
