我们回顾了最近关于多铁性锰矿磁和磁电激发的实验结果，特别关注斜方 RMnO3（R = 稀土）。由于被称为电磁子的新型磁电激发的存在，这些材料的动力学最近引起了特别关注。除了电磁子的强电活动之外，在与电磁子相同的频率范围内观察到一系列其他磁和磁电性质的激励。我们总结了现有模式的系统性以及当前对底层机制的理解。
We review the recent experimental findings concerning the magnetic and magnetoelectric excitations in multiferroic manganites with special focus on orthorhombic RMnO3 (R = rare earth). The dynamics of these materials has attracted special attention recently due to the existence of novel magnetoelectric excitations which were termed electromagnons. In addition to the strong electric activity of the electromagnons, a series of other excitations of magnetic and magnetoelectric nature is observed in the same frequency range as the electromagnons. We summarize the systematics of the existing modes and the current understanding of the underlying mechanisms.
