研究了 Co 和 Ni 替代 Fe 对以六方 Fe2P 型结构结晶的 MnFe(P,Ge) 化合物磁热性质的影响。研究发现，通过改变成分，当磁转变被控制在接近一级和二级转变区的边界时，MnFe(P,Ge)化合物可以同时获得小的热滞和巨磁热效应。
The effect of Co and Ni substitutions for Fe on the magnetocaloric properties of MnFe(P,Ge) compounds crystallizing in the hexagonal Fe2P type of structure was studied. It was found that, by changing composition, a small thermal hysteresis and a giant magnetocaloric effect can be obtained simultaneously in MnFe(P,Ge) compounds when the magnetic transition is controlled to be close to the border separating the first- and second-order transition regimes.
