论文摘要
我们通过在界面上掺入超薄FE层，在稀释液/正常金属多层中的Rkky Interlayer交换的强度增强了20倍。此外，界面磁化极化的产生增加会深刻影响有限尺寸的效果，从而锐化了多层的库里过渡，同时允许通过内层磁性稀释分别调整其库丽温度。这些结果对于设计用于在磁含量微观冻结和热辅助自旋电子学的功能材料方面应该很有用。
We demonstrate a 20-fold enhancement in the strength of the RKKY interlayer exchange in dilute-ferromagnet/normal-metal multilayers by incorporating ultrathin Fe layers at the interfaces. Additionally, the resulting increase in the interface magnetic polarization profoundly affects the finite-size effects, sharpening the Curie transition of the multilayer, while allowing to separately tune its Curie temperature via intralayer magnetic dilution. These results should be useful for designing functional materials for applications in magneto-caloric micro-refrigeration and thermally-assisted spin-electronics.
