Room temperature multiferroicity in orthorhombic LuFeO3
Abstract
From the measurement of dielectric, ferroelectric, and magnetic properties we observe simultaneous ferroelectric and magnetic transitions around 600 K in orthorhombic LuFeO3. We also observe suppression of the remanent polarization by 95\% under a magnetic field of 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 LuFeO3 is a room temperature multiferroic of type-II variety exhibiting quite a strong coupling between magnetization and polarization.
