Abstract

Topology plays a crucial and multifaceted role in solid state physics, leading to a remarkable array of newly investigated materials and phenomena. In this Perspective, we provide a brief summary of well-established model materials with a particular focus on compensated magnets and highlight key phenomena that emerge due to the influence of topology in these systems. The overview covers various magneto-transport phenomena, with a particular focus on the extensively investigated anomalous magneto-transport effects. Furthermore, we look into the significance of topology in understanding elementary magnetic excitations, namely magnons, where the role of topology gained considerable attention from both theoretical and experimental perspectives. Since electrons and magnons carry energy, we explore the implications of topology in combined heat and spin transport experiments in compensated magnetic systems. At the end of each section, we highlight intriguing unanswered questions in this research direction. To finally conclude, we offer our perspective on what could be the next advancements regarding the interaction between compensated magnetism and topology.

拓扑结构在补偿磁性系统中的作用

拓扑学在固态物理学中发挥着关键和多方面的作用，带来了一系列令人瞩目的新研究材料和现象。在本《视角》中，我们简要概述了成熟的模型材料，尤其关注补偿磁体，并重点介绍了这些系统中由于拓扑结构的影响而出现的关键现象。概述涵盖了各种磁传输现象，尤其侧重于广泛研究的反常磁传输效应。此外，我们还探讨了拓扑学在理解基本磁激发（即磁子）方面的意义，拓扑学在这方面的作用从理论和实验角度都获得了相当大的关注。由于电子和磁子都携带能量，我们探讨了拓扑学在补偿磁系统的热量和自旋传输联合实验中的意义。在每一节的最后，我们都会强调这一研究方向中有趣的未解之谜。最后，我们对补偿磁性与拓扑学之间的相互作用的下一步进展提出了自己的看法。
