摘要:

我们发现,通过微磁学模拟的运动的一个横向壁(TW)型的磁薄膜纳米条纹的畴壁可以操纵通过TW传播的自旋波(SW)通过相互作用。TW运动的速度可以通过改变传播SW的频率和幅度来控制。此外,TW运动由与TW结构内部存在的局部模式的谐振频率一致的特定SW频率有效地驱动。使用传播SW(其频率被调谐到固有TW模式的频率)是控制纳米条纹中TW运动的另一种方法。

英文摘要:

We found by micromagnetic simulations that the motion of a transverse wall (TW) type domain wall in magnetic thin-film nanostripes can be manipulated via interaction with spin waves (SWs) propagating through the TW. The velocity of the TW motion can be controlled by changes of the frequency and amplitude of the propagating SWs. Moreover, the TW motion is efficiently driven by specific SW frequencies that coincide with the resonant frequencies of the local modes existing inside the TW structure. The use of propagating SWs, whose frequencies are tuned to those of the intrinsic TW modes, is an alternative approach for controlling TW motion in nanostripes.
