摘要

Co-X(X=Cr,Mo,W) magnetic thin films were prepared by using DC magnetron sputtering,and their structures were examined by using X-ray diffraction(XRD).The amorphous forming ability(AFA) of the three alloy systems was discussed based on thermodynamic calculation and experiments.The results show that the Co-Mo thin films exhibit the largest AFA among them,and the Co-W thin films are conditiondependent amorphous while the Co-Cr thin films are hard to be amorphous,which is consistent with the thermodynamic calcu...
