采用电沉积技术与半导体材料相结合，在 GaAs（100）单晶表面制备了表面光亮、致密、平整的坡莫合金薄膜。用 X 射线荧光技术与线偏振 X 射线吸收谱(XAS)确定了薄膜的组成为 Fe21Ni79。磁光克尔效应(MOKE)测量结果表明样品薄膜具有典型的软磁性能。采用元素分辨的X射线磁性圆二色(XMCD)技术得到了合金薄膜中各元素的圆二色谱，利用加和定则计算了Fe和Ni的自旋磁矩和轨道磁矩，结果表明薄膜的磁性主要来源于Fe和Ni的自旋磁矩。

Permalloy films with bright, dense and smooth surface were deposited on semiconductor GaAs (100) single-crystal surface using electrodeposition technology. The composition of permalloy thin films was identified as Fe21Ni79 by X-ray fluorescence and linearly polarized X-ray absorption spectroscopy(XAS). The Magneto-optical Kerr effect(MOKE) results suggest that Fe21Ni79 thin films are typical soft-magnetic material. Circular dichroism spectra of each element were obtained by element-specific X-ray magnetic circular dichroism (XMCD) technology. The spin and orbit moment of Fe and Ni element was calculated by the sum rule and the results reveal that the magnetism of the thin films come from the spin moment of Fe and Ni.
