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.

Altermagnetism： Exploring New Frontiers in Magnetism and Spintronics（交替磁性：探索磁学和自旋电子学的新领域）


最近的发展引入了一种开创性的共线磁性形式，称为“altermagnetism”。这种新兴的磁相的特点是稳健的时间反转对称性打破、反平行磁序和交替的自旋分裂能带结构，但它表现出受对称性约束的消失净磁化强度。交替磁性独特地整合了以前被认为与传统共线铁磁性和反铁磁性互斥的特性，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。交替磁相的存在最初是从理论上提出的，此后被一系列实验研究证实，这些研究证实了其独特的特性和应用潜力。这篇综述探讨了关于互通磁体的快速扩展研究，强调了它们表现出的新物理现象、诱导互通磁的方法以及有前途的互通磁材料。本综述的目的是为读者提供对互磁的全面概述，并激发对互磁材料的进一步创新研究，这可能会彻底改变技术和材料科学的应用。
