霍尔效应是凝聚态领域中古老却又极具潜力的研究领域, 其起源可以追溯到数百年前. 1879 年, 霍尔发现将载流导体置于磁场中时, 磁场带来的洛伦兹力将使得电子在导体的一侧积累, 这一新奇的物理现象被命名为霍尔效应. 之后, 一系列新的霍尔效应被发现, 包括反常霍尔效应、量子霍尔效应、自旋霍尔效应、拓扑霍尔效应和平面霍尔效应等. 值得注意的是, 霍尔效应能够实现不同方向的粒子流之间的相互转化, 因此在信息传输过程中扮演着重要的角色. 在玻色子体系(如磁子)中, 相应的一系列磁子霍尔效应也被发现, 他们共同推动了以磁子为基础的自旋电子学的发展. 本文回顾了近年来在磁子体系中的霍尔效应, 简述其现代半经典的处理方法, 包括虚拟电磁场理论和散射理论等. 并进一步介绍了磁子霍尔效应的物理起源, 概述了不同类型磁子的霍尔效应. 最后, 对磁子霍尔效应的发展趋势进行了展望.Hall effect is an ancient but highly potential subfield in condensed matter physics, and its origin can be traced back hundreds of years. In 1879, Hall made a momentous discovery that when a current-carrying conductor is placed in a magnetic field, the Lorentz force pushes its electrons to one side of the conductor. This intriguing phenomenon was dubbed Hall effect. Since then, a series of novel Hall effects have been discovered, including anomalous Hall effect, quantum Hall effect, spin Hall effect, topological Hall effect, and planar Hall effec. Notably, Hall effects play an important role in realizing the information transport, since it can realize the mutual conversion of current in different directions. In bosonic systems such as magnons, a series of magnon Hall effects have been found, jointly driving the development of the magnon-based spintronics. In this perspective, we review the researches of the Hall effect in magnonic system in recent years, and briefly introduce its modern semi-classical theories, including virtual electromagnetic field theory and scattering theory. Furthermore, we introduce the different magnon Hall effects and clarify the physics behind them. Finally, the prospect of magnon Hall effect is discussed.
