对CsCuCl3的磁化过程给出了理论解释，表明平行于c轴的外场有一个小的跳变。结果表明，量子涨落在S=1/2三角形反铁磁体中非常重要，它们可以改变基态自旋结构。观察到的磁化跳变被成功地解释为由量子效应引起的自旋翻转过程。
A theoretical interpretation is given on the magnetization process of CsCuCl3 showing a small jump for the external field applied parallel to the c-axis. It is shown that quantum fluctuations are so important in this S=1/2 triangular antiferromagnet that they can change the ground-state spin structure. The observed magnetization jump is successfully explained as a spin flop process caused by the quantum effect.
