用不同的材料(Co93Fe7和Fe)作衬底层,利用磁控溅射法成功制备了Fe65Co35(主层)/衬底层结构的双层薄膜.通过X射线衍射和磁性测量发现,在不同的衬底上沉积的Fe65Co35薄膜的织构不同,并且(200)取向的Fe65Co35薄膜的面内各向异性和软磁性优于(110)取向的Fe65Co35薄膜.通过典型样品的穆斯堡尔谱分析发现,Fe65Co35薄膜的磁化强度矢量具有一定的垂直分量,并且当Fe65Co35薄膜为(110)取向时磁化强度矢量的垂直分量比(200)取向时要大.进一步的研究发现,这种现象是由Fe65Co35薄膜与衬底层接触界面上应力诱导的界面各向异性导致的.
Using different materials (Co93Fe7 and Fe) as backing layer, a double layer thin film of Fe65Co35 (main layer) / backing layer structure was successfully prepared by magnetron sputtering method.From X-ray diffraction and magnetic measurement, The texture of the Fe65Co35 thin films deposited on the substrate is different, and the in-plane anisotropy and soft magnetic properties of (200) -oriented Fe65Co35 thin films are better than that of (110) -oriented Fe65Co35 thin films.Mosibor spectrum analysis of typical samples shows that Fe65Co35 The magnetization vector of the film has a certain vertical component, and the vertical component of the magnetization vector is larger when the Fe65Co35 film is (110) oriented than the (200) orientation.Further studies have found that this phenomenon is caused by the Fe65Co35 film and the liner Stress induced interface anisotropy on the underlying contact interface.
