作者研究了坡莫合金微带在微波辐射下的直流电阻变化。实验结果表明，自旋整流和测辐射热效应都会显着影响直流电阻变化，并且由于它们对微波调制频率的不同依赖性，可以精确确定两者的贡献。因此，可以获得磁化进动锥角和微波加热后的热弛豫时间。
The authors have investigated the dc resistance change of a Permalloy microstrip under microwave irradiation. The experimental results demonstrate that both the spin-rectification and the bolometric effects significantly affect the dc resistance change, and the contribution of each can be precisely determined due to their different dependences on the modulation frequency of the microwave. Therefore, both the cone angle of magnetization precession and the thermal relaxation time following microwave heating are obtained.
