Description
Summary:Single-phase multiferroics that allow the coexistence of ferroelectric and magnetic ordering above room temperature are highly desirable, and offer a fundamental platform for novel functionality. In this work, a double perovskite multiferroic Pr<sub>2</sub>FeAlO<sub>6</sub> ceramic is prepared using a sol-gel process followed by a quenching treatment. The well-crystallized and purified Pr<sub>2</sub>FeAlO<sub>6</sub> in trigonal structure with space group R3c is confirmed. A combination of the ferroelectric (2P<sub>r</sub> = 0.84 μC/cm<sup>2</sup>, E<sub>c</sub> = 7.78 kV/cm at an applied electric field of 20 kV/cm) and magnetic (2M<sub>r</sub> = 433 memu/g, H<sub>c</sub> = 3.3 kOe at an applied magnetic field of 1.0 T) hysteresis loops reveals the room-temperature multiferroic properties. Further, the magnetoelectric effect is observed from the measurements of magnetically induced dielectric response and polarization. The present results suggest a new complex oxide candidate for room-temperature multiferroic applications.
