Abstract

Antiferromagnetic resonances (AFMR) of MgCu2O3 powder have been observed in the frequency region from 80 to 383.3 GHz using pulsed magnetic fields of up to 15 T at 1.8 K, which is well below the Néel temperature TN = (95 ± 1) K. Reflecting its two-dimensional character, easy-plane type anisotropy was observed and the observed results were analyzed by the conventional two-sublattice molecular field theory. Although the existence of Dzyaloshinsky-Moriya interaction was suggested by the previous neutron measurements, we were not able to resolve it from our AFMR results.
