Enhancement of nonlocal spin-valve signal using spin accumulation in local spin-valve configuration

摘要

We propose a nonlocal spin-valve measurement combined with a local spin-valve structure to enlarge spin signal. The probe configuration consists of a lateral spin valve with three Ni-Fe wires bridged by a Cu wire. The advantage is that the spin polarization in the Cu wire induced by the spin injection can be enhanced compared to the conventional method. (C) 2004 American Institute of Physics.
