本文综述了Ni 2 Mn_（1 + x）Sn_（1-x）和Ni 2 Mn_（1 + x）In_（1-x）三元合金的母相和马氏体相的磁性能以及NiCoMnIn合金的磁致形状记忆效应，并介绍了我们在NiCoMnSn合金粉末冶金方面的最新工作。NiMnSn合金中母相的总磁矩的浓度依赖性与NiMnIn合金中的母相的总磁矩的浓度依赖性非常不同，并且NiMnSn和NiMnIn合金中具有低磁化强度的马氏体相的磁性已被Mössbauer检验证实为顺磁性，但不是反铁磁性。采用放电等离子烧结技术制备的NiCoMnSn合金的塑性得到了显著的改善，并证实了其具有一定的变磁形状记忆效应。
The magnetic properties of the parent and martensite phases of the Ni2Mn1+xSn1-x and Ni2Mn1+xIn1-x ternary alloys and the magnetic field-induced shape memory effect obtained in NiCoMnIn alloys are reviewed, and our recent work on powder metallurgy performed for NiCoMnSn alloys is also introduced. The concentration dependence of the total magnetic moment for the parent phase in the NiMnSn alloys is very different from that in the NiMnIn alloys, and the magnetic properties of the martensite phase with low magnetization in both NiMnSn and NiMnIn alloys has been confirmed by Mössbauer examination as being paramagnetic, but not antiferromagnetic. The ductility of NiCoMnSn alloys is drastically improved by powder metallurgy using the spark plasma sintering technique, and a certain degree of metamagnetic shape memory effect has been confirmed.
