Abstract

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.
