用数值方法研究了不同自旋波模式和不同结构下自旋波(SW)包与磁畴壁(DW)的相互作用。微磁模拟表明，Neel型DW对所有三种不同的短波模式产生的相移Δφ几乎相同(0.4π~0.6π)，而在与Bloch型DW相互作用的情况下，Δφ显著增强。文中还给出了在脉冲微波电流作用下对短波感应相移的感应检测。
The interaction between the spin wave (SW) packet and the domain wall (DW) have been numerically studied for various spin wave modes and the DW structures. Micromagnetic simulations reveal that the Neel type DW causes practically similar phase shift Δφ (0.4π ~ 0.6π) for all of the three different SW modes, while the Δφ is considerably enhanced in the case of the interaction with the Bloch type DW. The inductive detection of the DW induced phase shift in the SW, emitted with a pulsed microwave current, is also demonstrated.
