我们表明，磁畴壁（DW）的旋转可以通过将直流电流注入到具有DW的磁线中来诱导。提出了一种利用电流诱导DW旋转产生微波的新型三端器件。微波的频率可以通过调节通过导线的电流密度来调谐，并且微波的幅度可以通过施加到磁性隧道结的直流偏压来调节。
We show that the rotation of a magnetic domain wall (DW) can be induced by the injection of a dc current into a magnetic wire with a DW. A novel three-terminal device that produces microwaves by utilizing the current-induced DW rotation is proposed. The frequency of the microwaves can be tuned by adjusting the current density through the wire, and the amplitude of the microwaves can be regulated through a dc bias applied to the magnetic tunnel junction.
