In the ferromagnetic resonance condition, the spin pumping driven by the dynamical exchange interaction of a permalloy film injects a pure spin current into the adjacent ZnO layer. This spin current gives rise to a DC voltage through the ISHE in the ZnO layer, and the DC voltage is proportional to the microwave excitation power. The effect is sizeable even when the spin backflow is considered. | 關聯: | Applied Physics Letters, 104(5), 052401 | 資料來源: | http://dx.doi.org/10.1063/1.4863750 | 資料類型: | article | DOI: | http://dx.doi.org/10.1063/1.4863750 |
