中文摘要：

稀磁半导体是指在非磁性化合物半导体中通过掺杂引入部分磁性离子所形成的一类新型功能材料.目前,稀磁半导体的磁性来源和机理一直是该领域的研究热点,掺杂的磁性离子通过怎样的交换方式实现铁磁性一直存有争议.本文对近几年来ZnO基稀磁半导体磁性机理研究进展作一综述,着重阐述了代表性的RRKY理论、平均场理论、双交换理论和磁极子理论,对实验和理论方面的热点和存在问题作一评价,对磁性理论的研究提出了新思路.

英文摘要：

Diluted magnetic semiconductors （DMSs） are new functional materials formed by doping a few percentages of magnetic ions in nonmagnetic semiconductors. Recently, the ferromagnetism origin and magnetism theory are the research hotspot in the field of DMSs. It is still unclear how the ferromagnetism is induced between the doped magnetic ions and the carriers. In this paper, the recent progress in magnetism theory was reviewed. The typical theories including RKKY, mean field theory, double exchange and bound magnetic polaron were elucidated in detail. The hotspot of experimental, theoretical research and existing problems were evaluated.
