摘要：

TmCd and TmZn exhibit pure quadrupolar structural phase transitions at 3.16 K and 8.55 K respectively. The magneto-elastic and quadrupolar coupling constants for these two compounds have been determined by different methods. The structural phase transition temperature Ta is strongly field dependent. We show the measured magnetic phase diagram Ta(B) together with the calculated one. The strong first order phase transitions at Ta are due to the Γ5 groundstate of the Tm3+-ion in these materials. © 1979.
