Abstract

We experimentally demonstrate that the ohmic contact of a Ni-Fe wire additionally connected to a Cu strip between an injector and detector in a nonlocal spin-valve structure signicantly suppresses the spin polarization induced in the Cu strip. This behavior is attributable to spin current absorption into the connected additional Ni-Fe wire.
