Abstract
The equilibrium spin configurations and antiferromagnetic resonance spectra of quasi-one-dimensional 'easy-plane' antiferromagnets on a triangular lattice are calculated. It is shown that in contrast to a simple two-sublattice antiferromagnet the spin reorientation in a transverse magnetic field is accompanied by a magnetic phase transition in relatively small fields, attributed to spin flip of two magnetic sublattices in the basal plane.Keywords
