MICROSTRUCTURE AND MAGNETISM OF[Co/Ti] AND [Co/Cu(Ni)] MULTILAYERS
[Co／Ti],[Co／Cu（Ni）]多层膜的结构与磁性

Two series of the multilayers with the forms of Co/Ti]30 andCo / 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 theCo/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.
