摘要
利用低温分子束外延技术(LT-MBE)制备的GaMnAs是一种新型的半磁半导体材料(DMS),它兼有磁性材料和半导体化合物的特点.系统地介绍了GaMnAs材料的结构、制备、居里温度、磁畴、磁矩、磁性质及几种多层异质结构,并对GaMnAs材料的应用、现状及前景作了简单的概括与分析.
GaMnAs is a kind of new Semimagnetic Semiconductor material prepared by Low-temperature molecular beam epitaxy, which combines the functionality of semiconductors with that of ferromagnetic materials. This paper introduced the structural properties, growth method, Curie temperature, magnetic domain, magnetic moment, magnetic properties and several multiplayer heterstructures related to GaMnAs systematically. In addition, The application, present situation and prospect was simply generalized and analysed.
