我们报道了Fe19Ni81薄膜的时间分辨传播自旋波谱。结果表明，自旋波包的幅度依赖于磁化方向，其相位可以由激发脉冲磁场的极性来控制。自旋波包的非互易发射可用于自旋波逻辑电路的二进制自旋波输入。
We report a time-resolved propagating spin wave spectroscopy for Fe19Ni81 film. We show that the amplitude of the spin-wave packet depends on the direction of magnetization and that its phase can be controlled by the polarity of pulsed magnetic field for the excitation. The nonreciprocal emission of spin-wave packet can be utilized for the binary spin-wave input into the spin-wave logic circuit.
