Abstract：The (Fe0.5Co0.5)68-xNb6B26Mox(x=0,0.5,1,2) amorphous alloy ribbons was prepared by melt-spinning method.The microstructural characteristics,thermal and magnetic properties of the amorphous alloy were investigated by means of X-ray diffractometer(XRD),differential scanning calorimeter(DSC)and vibrating sample magnetometer(VSM).The results show that the alloy with different Mo content has obvious vitrification transition stage and a crystallization process during the heating process.The addition of Mo element can improve the thermal stability and amorphous formability of the alloy.With the increase of Mo content x from 0 to 2,the initial crystallization temperature Tx increases from 884 K to 940 K,while the width ΔTx increases from 91 K to 104 K.The amorphous ribbons exhibit a typical soft magnetic alloy with low coercivity.With the increase of Mo content,Ms decreases from 81 emu·g-1 to 59 emu·g-1,which is mainly due to the decrease of magnetic moment caused by the antiferromagnetic coupling effect of Mo addition.
