本文在用磁化强度和应变分量表示的Landau型自由能函数的基础上，讨论了稀土Fe 2化合物族磁致伸缩合金的弹性刚度常数。研究发现，在四方-菱面体相变点附近，某些弹性刚度常数变得非常小。
Elastic stiffness constants in magnetostrictive alloys of the rare-earth Fe 2 compound family are discussed on the basis of the Landau-type free energy function expressed in terms of magnetization and strain components. It was found that some of elastic stiffness constants become extremely small in the vicinity of tetragonal-rhombohedral phase transition points.
