直流电压出现在经历铁磁共振的铁磁多层膜的两端和平面内。我们研究了在具有不同间隔层材料的铁磁/正常金属/铁磁三层膜中同时产生的直流电压和磁化进动的均匀模式的激励。所产生的电压强烈地依赖于正常金属间隔物的化学性质和厚度以及微波入射功率。这种直流电压可能与最近预测的自旋泵效应有关。(c)2005年美国物理学会。
Direct current voltage appears across and in plane of a ferromagnetic multilayer experiencing ferromagnetic resonance. We have investigated the dc voltage simultaneously generated with the excitation of the uniform mode of magnetization precession in ferromagnetic/normal-metal/ ferromagnetic trilayers with different spacer-layer materials. The generated voltage strongly depends on the chemical nature and the thickness of the normal-metal spacer as well as on the microwave incident power. This dc voltage might be correlated with the spin-pumping effect recently predicted. (c) 2005 American Institute of Physics.
