The effect of fe and metalloid contents on magnetic properties of fe–si–b–p amorphous alloys containing fe in the range of 83-85 at%

A series of Fe–Si–B–P amorphous alloys with high Fe content in the range of 83-85 at.% were successfully pre-pared through a melt-spinning technique. The effects of Fe content and metalloid elements on thermal and magnetic properties of Fe–Si–B–P amorphous alloys were studied. The saturation magnetization (M_s) values of amorphous alloys tend to decrease with the increase of Fe content higher than 83 at%. For a given Fe content, the replacement of Si or B by P results in a decrease of the M_s value. When the P content more than 5 at.%, the M_s value of the ribbon rapidly decreases. In addition, the compositional dependence of the thermal and magnetic properties has been discussed.
