Mn3CuN中超过2000 ppm的超磁致伸缩的发现，刺激了从强迫磁致伸缩角度对锰反钙钛矿的研究。我们发现，在居里温度 TC = 360 K 以下，Mn3SbN 在四方扭曲铁磁相中表现出高达 450 ppm 的大磁致伸缩。通过部分替换组成元素，磁致伸缩的幅度增强了高达 1000 ppm，且 TC 没有降低。目前的结果是根据铁磁形状记忆效应进行检验的。
The discovery of giant magnetostriction exceeding 2000 ppm in Mn3CuN has stimulated the research of manganese antiperovskites from the perspective of forced magnetostriction. We discovered that Mn3SbN exhibits a large magnetostriction of up to 450 ppm in the tetragonally distorted ferromagnetic phase below the Curie temperature TC = 360 K. The magnitude of magnetostriction is enhanced by up to 1000 ppm without reduction of TC by partial replacement of the constituent elements. The present results are examined in terms of ferromagnetic shape memory effects.
