We examine the high-frequency optical mode of {\alpha}-Fe2O3 and report thatDzyaloshinskii-Moriya (DM) interaction generates a new type of torque on themagnetic resonance. Using a continuous-wave terahertz interferometer, wemeasure the optical mode spectra, where the asymmetric absorption with a largeamplitude and broad linewidth is observed near the magnetic transition point,Morin temperature (TM ~ 254.3 K). Based on the spin wave model, the spectralanomaly is attributed to the DM interaction-induced torque, enabling to extractthe strength of DM interaction field of 4 T. Our work opens a new avenue tocharacterize the spin resonance behaviors at an antiferromagnetic singularpoint for next-generation and high-frequency spin-based informationtechnologies.
