摘要：

Specific heat, susceptibility, and magnetization measurements were performed on a random mixture of two antiferromagnets with competing spin anisotropies, FeCl2•2H2O and CoCl2•2H2O. From these experiments, the concentration versus temperature phase diagram is obtained, which shows clearly the existence of a tetracritical point. The phase diagram is compared with those obtained by recent renormalization-group analysis and mean-field theories. © 1979 The American Physical Society.
