ResumoHigh-field magnetization of two hexagonal layered compounds RbFe(MoO 4 ) 2 and CsFe(SO 4 ) 2 is measured. In the magnetization curves of both compounds, a plateau-like structure with one-third of the saturated moment is observed. This anomaly is analyzed in terms of the magnetization process of a two-dimensional triangular lattice Heisenberg antiferromagnet with weak Ising-type anisotropy.
