| 摘 要： | 利用同步辐射和铁磁共振研究了经硫代乙酰胺硫钝化处理的ＧａＡｓ（１００）表面生长的Ｆｅ，Ｃｏ超薄膜与衬底的界面形成及磁性。实验结果表明，硫钝化能阻止Ａｓ向Ｆｅ，Ｃｏ超薄膜扩散，减弱Ａｓ和Ｆｅ，Ｃｏ的相互作用并增强在ＧａＡｓ（１００）表面生长的铁磁金属薄膜的磁性。

| Abstract: | s: The interface formation and magnetism of Fe, Co overlayer on sulfur passivated GaAs(100) by using CH 3CSNH 2 have been studied with synchrotron radiation photoemission (SRPES) and ferromagnetic resonance (FMR). The experimental results show that sulfur passivation can prevent As from diffusing into Fe and Co overlayer and weaken the reactions of As with Fe and Co, which enhances the magnetism of Fe, Co thin films grown on GaAs(100). |
