Hexagonal HoMnO3 is a very important and representative material in the field of multiferroic magnetoelectric research recently.In this paper,the magnetoelectric properties and the study progress of hexagonal HoMnO3 at home and abroad were reviewed comprehensively,which included spin exchange interactions at low temperature,magnetic phase transitions,changes of the magnetization induced by an applied electric field,the mechanism of ferroelectric polarization,and giant magnetoelectric effect induced by magnetoelastic,spin-lattice coupling,spin-phone coupling,and so on.Special emphasis was given to the physical machanism of magnetoelectric effect of HoMnO3.Based on these,the existing problems in the application research of HoMnO3 were evaluated and the possible way to solve these problems was proposed.
