我们的实验表明，一个Ni-Fe线的欧姆接触，另外连接到一个Cu带之间的注入器和检测器的非局部自旋阀结构显着抑制自旋极化在Cu带中诱导。这种行为归因于自旋电流吸收到连接的附加Ni-Fe线中。
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.
