Co—Nb/Cr磁性多层膜由高频溅射方法制得由振动样品磁强计测量作品的磁性能在2.67Pa溅射氩气压下,发现样品随Cr层厚度增加,铁磁层间出现铁磁性和反铁磁性的耦合振荡,饱和磁化强度Ms基本保持不变,而在0.67Pa溅射氩气压下,样品的饱和磁化强度Ms发生了振荡,这可能与其铁磁层中顺磁分量振荡变化有关.
Co-Nb/Cr multilayered films were prepared with the rf-sputtering method. The magnetic properties of the samples were studied by a micropro cessor-controlled vibrating-sample magnetometer. When the charging Ar pressure PAr=2.67 Pa, an oscillation between ferromagnetic and antiferromagnetic coupling with the thickness of Cr layers was found, and the spontaneous magnetization Ms remains constant basically. When PAr=0.67 Pa, the value of Ms shows an oscillatory behaviour, which may be related to the oscillatory variation of the paramagnetic component in the ferromagnetic layers.
