对畸变三角形晶格反铁磁体RbCoBr3进行了高场磁化测量。磁化曲线出现dM/dH两个峰的异常。这些峰值位置的温度依赖性接近磁相变点atH= 0。结果表明，即使在有限的磁场中，也可能出现中间磁相，即部分无序相。
High-field magnetization measurements were performed on a distorted triangular-lattice antiferromagnet, RbCoBr3. The magnetization curve shows anomalies characterized by two peaks of dM/dH. The temperature dependences of these peak positions approach the magnetic phase transition points atH= 0. The results suggest that an intermediate magnetic phase, which is known as the partial disordered phase, may appear even in a finite magnetic field.
