预计进动铁磁体将通过欧姆接触将自旋电流注入相邻导体，而不管电导是否与例如掺杂半导体不匹配。这为通过铁磁共振创建纯自旋源（“自旋电池”）开辟了道路。我们估计不同材料组合的自旋电流和自旋偏置。
Precessing ferromagnets are predicted to inject a spin current into adjacent conductors via Ohmic contacts, irrespective of a conductance mismatch with, for example, doped semiconductors. This opens the way to create a pure spin source ("spin battery") by the ferromagnetic resonance. We estimate the spin current and spin bias for different material combinations.
