The amorphous CoZr soft magnetic films with superior properties were prepared by radio-frequency sputtering under pressure of 0.5Pa Ar.The saturation magnetization of the amorphous CoZr films with relation to the Zr content and temperature was investigated.The amorphous CoZr films composed of different constituents obey the Bloch T~(3/2)-low in a wide range of temperatures.The number of electrons transferred from each Zr atom to 3d energy band of Co calculated by the rigid band model is about 2.27.
