在本工作中，Fe_（80-x）M_xP_（13）C_7（M = Co，Ni; x = 0，5和10at.%）制备了大块非晶合金，系统研究了Co/Ni元素替代Fe对Fe_（80）P_（13）C_7大块非晶合金磁热性能的影响。随着Co/Ni替代Fe，铁基块体玻璃的居里温度（TC）升高。铁基非晶合金的磁熵变（ΔSM）随Co取代Fe量的增加先增大后减小，随Ni取代Fe量的增加而单调减小。在目前的铁基BMG中，Fe 75 Co 5 P13 C7 BMG在5 T的外加磁场下表现出5.21 J kg-1 K-1的最大ΔSM值，这是迄今为止报道的不含任何稀土元素的铁基非晶合金中的最大值。铁基非晶合金具有较大的非晶形成能力、可调的相变温度和较高的ΔSM值，这对磁制冷材料的研究具有重要意义。
In this work, Fe80-xMxP13C7 (M = Co, Ni; x = 0, 5 and 10 at.%) bulk metallic glasses (BMGs) were prepared, and the effect of the Co/Ni elements substitution for Fe on the magnetocaloric properties of Fe80P13C7 BMG has been investigated systematically. The Curie temperature (TC) of the present Fe-based BMGs increases with the substitution of Fe by Co/Ni. The magnetic entropy change (ΔSM) of the present Fe-based BMGs increases first and then decreases with the increase of Fe substituted by Co, but monotonically decreases with the increase of Fe substituted by Ni. Among the present Fe-based BMGs, the Fe75Co5P13C7 BMG exhibits the maximum ΔSM value of 5.21 J kg−1 K−1 at an applied field of 5 T, which is the largest value among Fe-based amorphous alloys without any rare earth elements reported so far. The present Fe-based BMGs exhibit the large glass forming ability, tunable TC and enhanced ΔSM value, which are beneficial for magnetic refrigerant materials.
