我们研究了绝缘磁/金属系统中基于自旋霍尔磁阻(SMR)的磁化动力学的直流整流效应对自旋泵浦测量的影响。我们从理论上发现，SMR的整流效应与自旋抽运的逆自旋霍尔效应具有不同的面内磁化角依赖关系。整流效应的贡献可以忽略不计，在腔测量中得到了实验证实。
We investigate a dc rectification effect of magnetization dynamics based on spin Hall magnetoresistance (SMR) in an insulating magnet/metal system on spin pumping measurements. We theoretically find that the rectification effect by SMR has different in-plane magnetization angle dependence from that of the inverse spin Hall effect on the spin pumping. The negligible contribution from the rectification effect is experimentally confirmed in a cavity measurement.
