Chirality of magnons is an intrinsic degree of freedom that characterizes the handedness of spin precession around its equilibrium direction. This commentary summarizes recent progress on spin pumping by ferromagnetic resonance in magnetic heterostructures. In particular, the commentary highlights one fundamental issue in spin pumping: the chirality dependence of the spin current.
手性是磁振子的一个内在自由度,它描述了自旋围绕其平衡方向进动的手性。本篇评论总结了磁性异质结构中通过铁磁共振进行自旋输运的最新进展。特别地,本篇评论强调了自旋输运中的一个基本问题:自旋流的手性依赖性。
