| 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Ｃｉｕ－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的增国发生振荡变化；在以非晶Ｃｏ和Ｔｉ构成的「Ｃｏ／Ｔｉ」多层膜中，ＭＳ和则随ｄｓ的增加而减小。

| Abstract: | 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. |
