摘要：

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.
