霍尔效应是凝聚态物理中一个古老但极具潜力的子领域，其起源可以追溯到数百年前。 1879 年，霍尔做出了一项重大发现：当将载流导体置于磁场中时，洛伦兹力会将其电子压向导体的一侧。这种有趣的现象被称为霍尔效应。随后，一系列新型霍尔效应被发现，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、平面霍尔效应等。值得注意的是，霍尔效应在信息传输中发挥着重要作用，因为它可以实现不同方向电流的相互转换。在磁振子等玻色子系统中，发现了一系列磁振子霍尔效应，共同推动了基于磁振子的自旋电子学的发展。从这个角度出发，我们回顾了近年来磁振子系统中的霍尔效应，简要描述了其现代半经典理论，包括虚拟电磁场理论和散射理论等。此外，我们介绍了不同的磁振子霍尔效应并阐明了它们背后的物理原理。最后对磁振子霍尔效应的前景进行了展望。
Hall effect is a ancient but highly potential subfield in condensed matter physics, its origin dates back hundreds of years. In 1879, Hall made the momentous discovery that when a current-carrying conductor is placed in a magnetic field, the Lorentz force presses its electrons against one side of the conductor. This intriguing phenomenon was dubbed as Hall effect. Afterwards, a series of novel Hall effects were discovered, including anomalous Hall effect, quantum Hall effect, spin Hall effect, topological Hall effect, and planar Hall effect, etc. Notably, Hall effects play an important role in information transport, since it enables the mutual transformation of current with 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 Hall effect in magnonic systems in recent years, briefly describe its modern semi-classical theories, including fictitious electromagnetic field theory and scattering theory, etc. Furthermore, we introduce the different magnon Hall effect and clarify the physics behind them. Finally,the prospect of magnon Hall effect is discussed.
