摘要：

采用循环伏安法在GaAs(100)单晶表面电沉积了铁族金属单质薄膜. 扫描电子显微镜(SEM)结果显示, Fe族金属薄膜的晶粒较小, 薄膜平整度较高。通过X射线衍射(XRD)谱分析了Fe, Co, Ni在GaAs(100)晶面上的外延生长. 使用磁光克尔效应装置研究了Fe族金属薄膜的宏观磁性, 用同步辐射圆偏振软X射线测量了铁族单质磁性薄膜的吸收谱, 获得了X射线磁性圆二色谱, 并通过加和定则计算了磁性薄膜中Fe族金属原子的轨道磁距和自旋磁矩.

Abstract:

Fe-group element magnetic films were electrodeposited on single crystal GaAs(100) surface via cyclic voltammetry. The results of scanning electron microscopy(SEM) indicated that the grain sizes of the films were small and the surface of the films was very smooth. The growth relation of Fe-group films electrodeposited on GaAs surface was analyzed systematically according to the X-ray diffraction(XRD) results. The macro-scopic magnetism of the magnetic films was measured with the magneto-optic Kerr effect device. X-ray magnetic circular dichroism(XMCD) spectra of Fe-group films were obtained from X-ray absorption spectra(XAS) via synchrotron radiation circularly polarized soft X-ray. According to the sum rules, the orbital and the spin magnetic moments of the element were calculated.

Key words: Electrodeposition, Magnetic film, X-Ray magnetic circular dichroism, Magnetic moment
