Popis:	Submillimeter wave ESR measurements of the ABX 3 triangular antiferromagnet CsMnBr 3 with easy-plane type anisotropy have been performed in the frequency region from 9 to 383.3 GHz. The frequency-field relations of AFMR observed below T N =8.3 K are analyzed by the molecular field theory using six sublattice model. To explain the AFMR modes, it is necessary to consider the diagonal interchain interaction J 2 as in the cases of the easy-axis type triangular antiferromagnets.
