Anisotropic manipulation of subterahertz spin waves by spin orbit torque in the antiferromagnetic orthoferrite

We theoretically and numerically elucidate the electrical control over spin waves in antiferromagnetic (AFM) orthoferrite with biaxial anisotropies and Dzyaloshinskii-Moriya interactions. In orthoferrites, a canted AFM manifests as a bifurcated spin wave dispersion relation with distinct high-freque...
