论文摘要

在铁,铁和抗铁磁铁中产生的自发磁序源于各种磁相互作用。根据Heisenberg交换相互作用,Dzyaloshinskii-Moriya交换相互作用,磁性偶性相互作用和晶体各向异性之间的相互作用和竞争,可以稳定多种磁纹理,例如磁性结构域壁,涡流,天空和螺旋螺旋结构。尽管这些自旋纹理中的每一个都以特殊的方式响应外部力,但它们还与磁子,磁性的基本集体激发相互作用,磁性的基本集体激发可以在无电荷传输的磁性材料中传播,因此可以散发出低的能量消散。最近的理论和实验发现,自旋波和磁纹理之间的相互作用特别有趣,并且富含物理学。在这篇综述中,我们介绍并讨论了生活在磁性纹理背景上的镁质的理论框架,以及通过磁纹理操纵镁质的最新实验进步。讨论了磁纹理的灵活性和可重新配置性,讨论了基于磁蛋白的信息处理方案中应用的潜力。

The spontaneous magnetic orders arising in ferro-, ferri- and antiferromagnets stem from various magnetic interactions. Depending on the interplay and competition among the Heisenberg exchange interaction, Dzyaloshinskii-Moriya exchange interaction, magnetic dipolar interaction and crystal anisotropies, a great variety of magnetic textures may be stabilized, such as magnetic domain walls, vortices, Skyrmions and spiral helical structures. While each of these spin textures responds to external forces in a specific manner with characteristic resonance frequencies, they also interact with magnons, the fundamental collective excitation of the magnetic order, which can propagate in magnetic materials free of charge transport and therefore with low energy dissipation. Recent theories and experiments found that the interplay between spin waves and magnetic textures is particularly interesting and rich in physics. In this review, we introduce and discuss the theoretical framework of magnons living on a magnetic texture background, as well as recent experimental progress in the manipulation of magnons via magnetic textures. The flexibility and reconfigurability of magnetic textures are discussed regarding the potential for applications in information processing schemes based on magnons.
