Spin wave Doppler Shift by Spin Transfer Torque in FerromagneticNanowires with a Domain Wall

摘要

@@ Introduction Recently, the magnetic domain wall (DW) dynamics in ferromagnetic nanowires by the spin-transfer torque (STT) or the propagating spin wave are actively studied due to the possibility of next generation memory applications and interesting underlying physics. For better understanding of the spin dynamics related to the DW motion, we have investigated the interaction between spin polarized current and the DW by employing micromagnetic simulations. In this study, we found that STT induced
