Abstract
We investigate the effects of a diagonal interchain interaction J 2 on the ESR modes in the ABX3-type antiferromagnets with easy-axis anisotropy.The static properties are described by replacing the conventional interchain interaction J1 by J1-2J 2. However, because of the phase difference between the sublattice magnetizations, J2 coupling produces marked effects on some ESR modes in cooperation with J1 coupling. Large separation between the ω1-mode and EPR line for H ⊥ c and ω2- and ω3-modes for H ∥ c (H>HSF) can be derived by maintaining consistency with the canting angle of spins from the c-axis and the spin wave dispersion at zero field. ESR measurements in CsMnI3 are reported. The frequency-field diagram obtained is described well by the model involving J2 coupling.
