摘　　要：Ni-Mn基Heusler合金是一种新型的磁性功能材料。在磁场或者温度诱导下,该类合金可以发生热弹性马氏体相变或者磁场诱发的孪晶再取向,导致其在相变温度附近具有磁致应变,磁热,磁电阻等众多新颖的物理效应。本文主要讨论现阶段Ni-Mn基Heusler合金在磁致应变以及磁热效应方面的研究进展,研究整理了该现阶段该合金相关研究的现状及其存在的问题,相关研究结论可为Heusler合金的后续研究提供有益参考。Ni-Mn based Heusler alloys are a new type of magnetic functional materials. Under the induction of magnetic field or temperature, these types of alloys can undergo thermoelastic martensitic phase transformation or magnetic field-induced twin reorientation, resulting in magnetic-field-induced strain, magnetocaloric, magnetoresistance and many other novel physical characteristics near the phase transition temperature. This article mainly discusses the current research progress of Ni-Mn-based Heusler alloys in terms of magnetic-field-induced strain and magnetocaloric effects. The research summarizes the current status of alloys related research and existing problems at this stage. The relevant research conclusions can be the Heusler alloys Follow-up research provides useful reference.
