Abstract

We investigate the effects of a diagonal interchain interaction J2 on the ESR modes in the y4&Y3-type antiferromagnets with easy-axis anisotropy. The static properties are described by replacing the conventional interchain interaction Jx by However, because of the phase difference between the sublattice magnetizations, J2 coupling produces marked effects on some ESR modes in cooperation with Jx coupling. Large separation between the cormode and EPR line for Hi. c and co2- and y3-modes for H//c (HHSF) 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.
