Abstract

From the measurement of dielectric, ferroelectric, and magnetic properties we observe simultaneous ferroelectric and magnetic transitions around $\sim$ 600 K in orthorhombic LuFeO $_3$ . We also observe suppression of the remanent polarization by $\sim$ 95\% under a magnetic field of $\sim$ 15 kOe at room temperature. The extent of suppression of the polarization under magnetic field increases monotonically with the field. These results show that even the orthorhombic LuFeO $_3$ is a room temperature multiferroic of type-II variety exhibiting quite a strong coupling between magnetization and polarization.
