Title: Terahertz absorption spectroscopy study of spin waves in orthoferrite YFeO 3 in a magnetic field

Abstract

We measured absorption of THz radiation in YFeO 3 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 Γ 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 et al., Phys. Rev. B 89, 014420 (2014)] and quantified the parameters of Dzyaloshinskii-Moriya interactions and single-ion anisotropies.
