Abstract
A 0.9(0.7BiFeO3–0.3BaTiO3–0.3 wt% MnO2)–0.1CoFe2O4 (BF–BT–CF) multiferroic ceramic composite was prepared and characterized. The composite showed well‐saturated polarization–electric field and magnetic hysteresis loops simultaneously at room temperature, with a remanent polarization of 15.7 μC/cm2 and a coercive field of 27 kV/cm. Spontaneous and remanent magnetizations of the BF–BT–CF composite were 6.7 and 0.87 emu/g, respectively. Its magnetoelectric voltage coefficient dE/dH was measured as a function of applied magnetic field at different frequencies. This ceramic composite might be a promising candidate as multiferroic materials displaying ferroelectricity, ferromagnetism, and magnetoelectricity.
