摘要: 用真空双源蒸镀法在玻璃衬底上制得了金属Fe/Pd成分调制膜。用X射线衍射分析了它们的调制特性和晶格结构;用振动样品磁强计进行磁性测量。结果表明:金属Fe/Pd成分调制膜中Pd层为fcc结构;随着Fe层厚度减小,Fe层结构由bcc转变为非晶态。研究了比饱和磁化强度随Fe层厚度的变化规律并探讨了它的机理。

关键词 ：成分调制膜, 调制结构, 比饱和磁化强度, Fe/Pd膜

Abstract：Fe/Pd compositionally modulated films (CMF) were prepared by vapour deposition from two sources onto glass substrate under vacuum. The modulation and crystal structures of the film were examined by X-ray diffaction. The magnetic properties were determined by vibrating sample magnetometer. The Pd layer in the Fe/Pd CMF is of fcc structure, and the Fe layer structure transits from bcc into amorphous state with decreasing thickness of Fe layer. The dependence of specific saturation magnetization on thickness of Fe layer has also been discussed.

Key words： compositionally modulated film modulated structure specific saturation magnetization Fe/Pd film
