用双对向靶溅射方法制备了具有非晶磁性的[Co/Ti]30,[Co/Cu(Ni)]30两组多层膜,分别用X射线衍射、透射电镜和振动样品磁强计做了结构和磁性测量在以非晶Co和Cu-Ni合金构成的[Co/Cu(Ni)]多层膜中,发现饱和磁化强度Ms随非磁性层厚度ds的增加发生振荡变化:在以非晶Co和Ti构成的[Co/Ti]多层膜中,Ms则随ds的增加而减小当ds>3nm时,两组多层膜的饱和磁化强度均趋向稳定,可用磁性多层膜层间耦合效应予以解释
Two sets of multilayer films of [Co / Ti] 30 and [Co / Cu (Ni)] 30 with amorphous magnetic properties were prepared by double-target sputtering and characterized by X-ray diffraction, transmission electron microscopy and magnetic field Structure and Magnetic Measurements In a [Co / Cu (Ni)] multilayer film made of amorphous Co and a Cu-Ni alloy, it was found that the saturation magnetization Ms oscillates with an increase in the thickness of the non-magnetic layer ds: In the [Co / Ti] multilayers composed of amorphous Co and Ti, Ms decreases with the increase of ds. When ds> 3nm, the saturation magnetization of the two groups of multilayers tends to be stable. The coupling effect between layers is explained
