标题： Newly discovered magnetic phase: A brief review on Altermagnets

摘要： 最近，一种新的磁相，称为交替磁性，引起了磁学和自旋电子学社区的关注。 这种新发现的磁现象不同于传统的铁磁性和反铁磁性。 它通常缺乏净磁化，并具有非相对论性的自旋分裂和破坏的时间反演对称性。 这导致了新颖的输运特性，如异常霍尔效应、晶体能斯特效应以及自旋依赖的现象，这些现象无法被传统磁性理论完全解释。 自旋依赖的现象，如自旋电流、自旋分裂力矩和高频动力学，成为交替磁体的关键特征。 本文通过提供理论研究和实验实现的概述，回顾了与交替磁体相关的主要方面。 我们讨论了交替磁性的最新进展、与其他磁序的比较，以及在未来下一代器件中利用其独特性质的前景。 显示英文摘要

摘要： Recently, a new magnetic phase, termed altermagnetism, has caught the attention of the magnetism and spintronics community. This newly discovered magnetic phenomenon differs from traditional ferromagnetism and antiferromagnetic. It generally lacks net magnetization and is characterized by unusual non-relativistic spin-splitting and broken time-reversal symmetry. This leads to novel transport properties such as the anomalous Hall effect, the crystal Nernst effect, and spin-dependent phenomena that cannot be fully explained by traditional magnetic theories. Spin-dependent phenomena such as spin currents, spin-splitter torques, and high-frequency dynamics emerge as key characteristics in altermagnets. This paper reviews the main aspects pertaining to altermagnets by providing an overview of theoretical investigations and experimental realizations. We discuss the most recent developments in altermagnetism, its comparison to other magnetic orders, and future prospects for exploiting its unique properties in next-generation devices.
