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。

关 键 词:饱和磁化强度 磁性 薄膜 多层膜

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.
Keywords:[Co/Ti] multilayer   [Co/Cu(Ni)] multilager   saturation magnetization.interlayer magnetic coupling   density of state
