摘要
过渡金属(TM)掺杂获得铁磁性ZnO基稀磁半导体(DMSs)的报道很多,但其铁磁性是否有微量磁性TM原子团簇或第二相的贡献存在争议。从磁性测量和磁性TM原子团聚及第二相的排除两方面综述了TM掺杂ZnODMSs本征铁磁性检证的常用方法,着重分析了元素特征分析技术在过渡金属掺杂ZnO中的应用。
Ferromagnetic ZnO-based diluted magnetic semiconductors（DMSs） by transition metal-doping has been reported in many literatures. However, whether there are magnetic contributions from some microcontent magnetic TM atoms cluster or secondary phase is still debated, Based on measuring of magnetic properties and exclusion of TM atoms cluster and the second phase, some typical techniques used to verify the intrinsic ferromagnetic of TMdoped ZnO DMSs have been reviewed and element specific analysis methods are discussed emphatically.
