摘要：

The magnetic phase diagram of CsMnBr3 has been determined from precise magnetization measurements. The single transition occurring in zero field splits into two successive transitions in a finite field applied in the c-plane. This indicates that the zero-field Néel point TN=8.32 K is a tetracritical point. The crossover exponents evaluated suggest that the tetracritical behavior is governed by the n=2 chiral universality. © 1990, THE PHYSICAL SOCIETY OF JAPAN. All rights reserved.
