用膨胀法和应变计对多晶和单晶Ni2+XMn1�XGa合金的研究表明，在外加磁场的作用下，在马氏体相变温度范围内可以产生大的应变。在结构相变和磁相变耦合的化学成分样品中，磁场诱导的应变最大，即在同一温度下发生。
A study of polycrystalline and single crystalline Ni2+X Mn1�X Ga alloys by means of dilatometric and strain gage techniques shows that large strain can be induced in the temperature range of the martensitic transformation by application of an external magnetic field. The biggest strain induced by magnetic field was observed in the samples of chemical compositions where the structural and magnetic transitions couple, i.e. occur at the same temperature.
