半磁半导体
semimagnetic semiconductor
半磁半导体semim眼netie semieonduetor一类新型半导体材料。又称稀磁半导体。通常为A卜二M,B型合金,由组分为普通半导体化合物AB和组分为磁性半导体MB组成,其中组分为x的磁性离子M无规则地占据A的子格点。由于这类材料中存在顺磁离子,具有彼强的局域自旋磁矩,与局域顺磁离子相联系的3d“电子和类s(导带)、类P(价带)能带电子之间的自旋与自旋相互作用结果,产生一种新的交换作用,称为sP一d交换作用,使半磁半导体具有与普通半导体截然不同的性质。自1978年国际上首次报道以来的近15年中,这方面工作已有很大的进展。 结构与组分典型的半磁半导体材料体系是A扩一二Mnx砂型合金,其中M扩离子无规地取代化合物A,理中部分11族的子格点。如宽能隙的Cd卜二Mn二Te(S,Se)、Znl一xMnxTe(S,Se)和窄能隙的Hg;一,Mn二Te(S,Se)等。稳定单相的Cd卜xMnxTe具有闪锌矿结构,组分x值可高达0.77;Cdl一xMnxS为纤锌矿结构,组分x上限为0.45;Znl一xMnxse则在x(0.30为闪锌矿结构,而在0.30
