摘要
稀磁半导体(DMS)材料同时利用了电子的电荷和自旋属性,具有优异的磁、磁光、磁电等性能,在材料科学和未来自旋电子器件领域具有广阔的应用前景。系统地概述了SiC基DMS材料的研究进展,介绍了材料的制备方式、结构、性质、铁磁性起源的机理以及器件潜在的应用前景。结合本实验小组的研究工作,重点阐述了材料的结构以及磁性机制。
Diluted magnetic semiconductors （DMS） are expected to play an important role in material science and future spintronics. The charge and spin of electrons are accommodated into a single matter, resulting in excellent magnetism, magneto-optical characteristic, magnetoelectricity and other properties. Recent progress of SiC-based diluted magnetic semiconductors was briefly introduced. The preparation methods, configuration, properties, and the ferromagnetism origin mechanism of the materials and the potential applications of the device were described, with the focus on the structure of the materials and the magnetic mechanism.
