Antiferromagnetic resonances and magnetization of a canted antiferromagnet.
A two-sublattice model has been applied to a canted antiferromagnet including both Dzyaloshinsky-Moria interaction and double-exchange. Static magnetization and frequencies of the antiferromagnetic resonances (AFMR) were calculated for static magnetic fields along the principal crystallographic axes of an orthorhombic crystal. The experimental data for La(0.95)Sr(0.05)MnO3, which include magnetization, positions and excitation conditions of the AFMR modes can be well accounted for using the model calculations.
