磁电效应研究的历史与现状

Historical Progress of Research on Magnetoelectric Effect

铁电磁系统是指在某一温度范围内同时具有铁电有序和铁磁有序的体系,两种有序共存耦合导致的某些特有的物理性质近来倍受关注。由于对这类材料磁电耦合性质的研究源于人们对磁电体磁电性质的研究,因此文章着重从实验和理论两方面对磁电作用研究的历史背景、铁电磁系统自洽耦合性质研究现状做了分析、概括,并由此对铁电磁材料预期的应用前景进行了展望。

The ferroelectromagnetics, in which ferroelectric ordering and ferromagnetic spin ordering coexist spontaneously at low temperature, have been the object of intensive theoretical and experimental studies. The paper analyzes the historical background, present situation of magnetoelectric coupling properties from theoretical and experimental aspects in the ferroelectromagnetic system and predicts the applicable perspective of the ferroelectromagnetic materials.
