| 摘 要： | 采用磁控溅射法制备了Pd/Fe和Pd1-xFex/Fe多层膜.利用变换梯度磁强计测量了样品的Ms.发现层间耦合是铁磁性的，Ms具有长程振荡，周期为4ML.振荡的相位和周期在Pd0.966Fe0.034/Fe和Fd0.944Fe0.056/Fe系统中保持不变.就Pd/Fe多层膜中是否存在内层的Pd负极化和长程的铁磁耦合振荡进行了讨论，并分析了不同计算结果以及理论计算与实验结果之间存在差异的原因.关键词：

| Abstract: | Pd1-xFex/Fe multilayers (MLs) with x=0,0.34,0.056,0.071 have been prepared by magnetron sputtering. The measurement of saturation magnetization in Pd/Fe MLs in the range of Pd thickness from 4to 18 ML shiows that the interlayer couplings are ferromagnetic and Ms possesses a long-range oscillation with a period of 4 ML Pd. The oscillation phase and period in Pd0.966Fe0.034/Fe and Pd0.944Fe0.056/Fe multilayers remain unchanged as compared with their reference Pd/Fe multilayers. A discussion is given about discrepancy between theory and experiments, concerning with whether a negative polarization of Pd in inner spacer and a long-range ferromagnetic oscillation appears in Pd/Fe systems. |
