对e-Mn3Ga(71.4at%Mn)进行了磁化强度测量和X射线衍射实验，发现D019型六方结构在170K以下轻微变形为正交结构，并伴随着自发磁化强度的急剧增加。晶体的变形可能会增强对理想三角自旋组态的偏离。
Magnetization measurements and X-ray diffraction experiments have been made on e -Mn 3 Ga (71.4 at%Mn) having a triangular spin structure with a weak ferromagnetic component below 460 K. It has been found that the D0 19 -type hexagonal structure is slightly distorted to an orthorhombic structure below 170 K, and that the transition is accompanied by a steep increase of spontaneous magnetization. The crystal distortion may enhance the deviation from the ideal triangular spin configuration.
