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。
A metal Fe / Pd component modulation film was prepared on a glass substrate by a vacuum double-source evaporation method. Their modulation properties and lattice structure were analyzed by X-ray diffraction; magnetic measurements were made with a vibrating sample magnetometer. The results show that the Pd layer in the Fe / Pd film is fcc structure. With the decrease of Fe layer thickness, the structure of Fe layer changes from bcc to amorphous state. The variation law of specific saturation magnetization with the thickness of Fe layer was investigated and its mechanism was discussed.
