本文报道了反钙钛矿Mn3SbN在室温下磁致伸缩的发现。在居里温度（TC = 360 K）下，Mn3SbN从高温（高t）顺磁态转变为低t铁磁态，并伴有立方到四方的结构变形。在四方扭曲的FM相中，Mn3SbN表现出高达450 ppm的大磁致伸缩，这是由90 kOe磁场下的线性热膨胀估计的，同时缓慢降低温度。通过相同的程序估计的磁致伸缩增强到1000ppm，而不降低部分更换组成元素的工作温度。从铁磁形状记忆效应的角度对目前的结果进行了检验。
The discovery of magnetostriction at room temperature in the antiperovskite Mn3SbN is reported herein. Mn3SbN undergoes a phase transition from a high-temperature (high-T) paramagnetic state to a low-T ferromagnetic (FM) state at the Curie temperature of TC = 360 K, accompanied by a cubic-to-tetragonal structural deformation. In the tetragonally distorted FM phase, Mn3SbN exhibits large magnetostriction of up to 450 ppm, estimated from the linear thermal expansion under a magnetic field of 90 kOe while slowly reducing the temperature. The magnetostriction estimated by the same procedure is enhanced to 1000 ppm without reduction of the operating temperature by partial replacement of the constituent elements. The present results are examined in terms of ferromagnetic shape memory effects.
