Abstract :
Radiation of circularly polarized sub-THz wave due to spin precession was observed at room temperature. Nearly perfect conversion of the linear to circular polarized wave was realized around the natural resonances at 102 GHz. ε-type GaxFe2-xO3 are very prospective for magneto-optic devices.
