Experiment results indicate that the great effect of spontaneous magnetostriction leads to the thermal expansion anomaly phenomenon in a state of magnetism and the negative thermal expansion phenomenon at near Curie temperature.
实验表明在磁性状态下,强烈的自发磁致伸缩效应导致了Dy_2AlFe_(16-x)Mn_x化合物出现反常热膨胀现象,在居里温度附近表现出了负膨胀现象。
