Abstract

A theory is developed for triangular helicoidal antiferromagnetic structures due to the relativistic-exchange inhomogeneous Dzyaloshinskii-Moriya interaction in hexagonal crystals. The magnetic structure observed in the (Formula presented) system is explained, and the spin-wave spectrum and relaxation of spin waves are analyzed. The theoretical results are in agreement with experimental antiferromagnetic-resonance data.
