利用自旋整流效应，通过检测电子信号，研究了Ni0.8Fe0.2带材中的自旋波。通过曲折控制线，周期性磁场施加在条带上。自旋波模式强烈依赖于周期磁场。在短周期样品中，我们发现了周期磁场控制的自旋波耦合效应，可以用作可调谐自旋波滤波器。(C)2011年美国物理学会。[doi：10.1063/1.3584032]
Excited spin waves in Ni0.8Fe0.2 strips are studied by detecting electrical signals with the use of a spin rectification effect. Through a meander control line, a periodic magnetic field is applied on the strips. Spin wave modes strongly depends on the periodic magnetic field. In a short period sample, we find spin wave coupling effect controlled by the periodic magnetic field, which can be used as a tunable spin wave filter. (C) 2011 American Institute of Physics.
