A 0.9(0.7BiFeO(3)-0.3BaTiO(3)-0.3 wt% MnO2)-0.1CoFe(2)O(4) (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 mu C/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.
