摘要:

磁性skyrmions是拓扑保护的纳米尺度物体,是新型磁性和自旋电子器件的重要组成部分。在这里,我们研究了磁纳米线中自旋波驱动的skyrmion的动力学。结果表明:(i)skyrmion先加速,然后指数减速;(ii)它可以左右转弯;(iii)当skyrmion数为正(负)时,它总是向左(右)转弯.我们的结果将是自旋波驱动的Skyrmionic器件的基础。

英文摘要:

Magnetic skyrmions are topologically protected nanoscale objects, which are promising building blocks for novel magnetic and spintronic devices. Here, we investigate the dynamics of a skyrmion driven by a spin wave in a magnetic nanowire. It is found that (i) the skyrmion is first accelerated and then decelerated exponentially; (ii) it can turn L-corners with both right and left turns; and (iii) it always turns left (right) when the skyrmion number is positive (negative) in the T- and Y-junctions. Our results will be the basis of skyrmionic devices driven by a spin wave.
