Abstract

Recent developments have introduced a groundbreaking form of collinear magnetism known as “altermagnetism”. This emerging magnetic phase is characterized by robust time-reversal symmetry breaking, antiparallel magnetic order, and alternating spin-splitting band structures, yet it exhibits vanishing net magnetization constrained by symmetry. Altermagnetism uniquely integrates traits previously considered mutually exclusive to conventional collinear ferromagnetism and antiferromagnetism, thereby facilitating phenomena and functionalities previously not achievable within these traditional categories of magnetism. Initially proposed theoretically, the existence of the altermagnetic phase has since been corroborated by a range of experimental studies, which have confirmed its unique properties and potential for applications. This review explores the rapidly expanding research on altermagnets, emphasizing the novel physical phenomena they manifest, methodologies for inducing altermagnetism, and promising altermagnetic materials. The goal of this review is to furnish readers with a comprehensive overview of altermagnetism and to inspire further innovative studies on altermagnetic materials which can potentially revolutionize applications in technology and materials science.

超磁：探索磁学和自旋电子学的新前沿

最近的发展引入了一种被称为 "反向磁性 "的突破性共轭磁性形式。这种新出现的磁性阶段具有强大的时间反转对称性破坏、反平行磁序和交替的自旋分裂带状结构等特征，但它在对称性的约束下表现出消失的净磁化。反铁磁性独特地整合了以前被认为与传统的对偶铁磁性和反铁磁性相互排斥的特征，从而促进了以前在这些传统磁性类别中无法实现的现象和功能。改磁相的存在最初是在理论上提出的，后来得到了一系列实验研究的证实，这些研究证实了改磁相的独特性质和应用潜力。这篇综述探讨了迅速扩展的变磁体研究，强调了变磁体表现出的新物理现象、诱导变磁体的方法以及有前途的变磁体材料。这篇综述的目的是向读者提供有关变磁性的全面概述，并激发对变磁性材料的进一步创新研究，从而有可能彻底改变技术和材料科学的应用。
