论文摘要
手性旋转泵送是通过来自近距离纳米磁体的动态偶极弹性场中一半的铁磁膜或导体中单向旋转电流产生的。我们制定了通过单向行进波介导的磁体之间的远程手性相互作用的一般理论，例如在磁性膜中的自旋波或波导中的微波。激发磁铁发出的行进波可以被动态干扰效果完全捕获，最初是被动的磁铁。当两种磁体都被均匀的微波炉激发时，它们之间的手性相互作用会在其磁杆数中产生巨大的失衡。
Chiral spin pumping is the generation of a unidirectional spin current in half of ferromagnetic films or conductors by dynamic dipolar stray fields from close-by nanomagnets. We formulate a general theory of long-range chiral interactions between magnets mediated by unidirectional traveling waves, e.g., spin waves in a magnetic film or microwaves in a waveguide. The traveling waves emitted by an excited magnet can be perfectly trapped by a second, initially passive, magnet by a dynamical interference effect. When both magnets are excited by a uniform microwave, the chiral interaction between them creates a large imbalance in their magnon numbers.
