Abstract
We measured absorption of THz radiation in YFeO3 single crystals at a temperature of 3 K in the magnetic field up to 17 T applied in all three crystallographic directions. Two spin-wave modes were observed at the �� point with energies 1.2 meV (9.8 cm-1) and 2.4 meV (19.3 cm-1) in zero field. From the magnetic-field dependence of mode energies, we have refined the previously proposed model [S. E. Hahn, Phys. Rev. B 89, 014420 (2014)PRBMDO1098-012110.1103/PhysRevB.89.014420] and quantified the parameters of Dzyaloshinskii-Moriya interactions and single-ion anisotropies. ? 2018 authors.
