    Abstract:

    The effects of low melting point elements Cu, Al and Ga on the magnetic properties of Ce17Fe78B6 alloys prepared by melt spinning technique are studied. The addition of these elements decreases the saturation magnetization, while the coercivity increases to a certain extent. Among the additive elements, the addition of Cu and Ga optimize grain size distribution, Ga addition is the most effective way to improve the coercivity of Ce17Fe78B6 alloy. The recoil loop of Ce17Fe78B6 alloy is slightly open. The best overall magnetic properties are obtained for Ce17Fe77.25B6Ga0.75 alloy. Compared with the counterpart Ce-Fe-B alloy, the exchange coupling interaction between the grains of Ce-Fe-B-Ga alloy is enhanced. The recoil loops closes completely and the average recovery permeability decreases, which effectively enhances the resistance of Ce-Fe-B based alloys to external magnetic field interference.
