The multiferroic materials BiFeO and MnO exhibit coexisting magnetic order and ferroelectricity, and provide exciting platforms for new physics and potentially novel devices, where intriguing interplay between phonons and magnons exists. In this review, we paint a complete picture of bulk BiFeO together with orthorhombic and hexagonal MnO ( includes rare-earth elements and yttrium) by summarizing the dynamics of spin and lattice and their magnetoelectric coupling, as well as the methods of controlling these characteristics under non-equilibrium conditions, from experimental and simulation perspectives.
多铁性材料BiFeO₃和MnO₃展现出共存的磁有序和铁电性，为新物理和潜在的新型器件提供了令人兴奋的平台，其中存在着声子与磁振子之间有趣的相互作用。在这篇综述中，我们从实验和模拟的角度，通过总结自旋和晶格的动力学及其磁电耦合，以及在非平衡条件下控制这些特性的方法，描绘了块状BiFeO₃以及正交和六方MnO₃（包括稀土元素和钇）的全貌。
