摘 要: | 稀磁半导体(diluted magnetic semiconductor,DMS)是结合电荷导电性能与电子自旋,使材料同时具有铁磁性及导电性能的一类自旋电子学材料。找到性能优良、居里温度高于室温的DMS是过去十几年的研究热点。氧化锡(SnO2)是重要的氧化物稀磁半导体之一。过渡金属掺杂氧化锡体系已实现了室温铁磁性,有望成为制备自旋电子学器件的材料。本文主要介绍了氧化锡基DMS的研究进展及磁性来源,并对其未来的研究方向进行了展望。 |

Abstract: | Diluted magnetic semiconductor (DMS) is spintronic material that combines the two characters of the electrons: charge and spin, which make the material possess both ferromagnetic and conductive properties. Finding novel DMS with excellent performance and Curie temperature higher than room temperature is a research hotspot in the past decade or so. Tin oxide (SnO2) is one of the important oxide diluted magnetic semiconductors. Transition metal-doped tin oxide systems have achieved room temperature ferromagnetism, and are expected to be materials for the preparation of spintronic devices. The research progress and magnetic source of SnO2-based DMS are mainly discussed in details, and the future research direction is also prospected. |
