RhxFe2-xO3 solid-solution epitaxial thin films were prepared by pulsed laser deposition. The ferroelectricity of Rh0.15Fe1.85O3 thin film was presented by the result of piezoelectric force microscopy phase and amplitude loops measured at room temperature. Ferrimagnetism at room temperature is confirmed by the magnetic hysteresis loop. The coercive field of Rh0.15Fe1.85O3 thin film at 5K is 12 kOe, which is larger than that of epsilon-Fe2O3. Rh0.15Fe1.85O3 is confirmed to be a room temperature multiferroic material. (C) 2019 The Ceramic Society of Japan. All rights reserved.
