摘　　要：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。Two series of the multilayers with the forms of [Co/Ti]30 and[Co / Cu(Ni)]30 prepared by dual facing target sputtering at room temperature, consist ofamorphous Co magnetic layer and exhibit soft magnetic properties. The structural and magnetic properties of [Co/Cu(Ni)] and [Co/Ti] multilayers were examined as a function of thespacer layer thickness (dTi and dCu(Ni)) by XRD, TEM and VSM measurements. The saturation magnetization Ms of the [Co/Ti] multilayer was found to decrease with dTi, but for the[Co/Cu(Ni)] multilayers, the Ms was found to oscillate with dCu(Ni). The Ms approached toa constant value when dTi and dCu(Ni) thickened enough. This is the result of differentinterlayer magnetic coupling effects.
