Large Magnetodielectric Effect of BaTiO(3)–BaFe(12)O(19) Composites in a Low Magnetic Field

[Image: see text] A microwave sintering procedure has been developed to achieve high quality multiferroic composites of (1 – x)BaTiO(3)–xBaFe(12)O(19) (x = 0.05, 0.10, 0.15, and 0.20). X-ray diffraction, scanning electron microscopy, and impedance spectra indicate that BaFe(12)O(19) particles are is...

description [Image: see text] A microwave sintering procedure has been developed to achieve high quality multiferroic composites of (1 – x)BaTiO(3)–xBaFe(12)O(19) (x = 0.05, 0.10, 0.15, and 0.20). X-ray diffraction, scanning electron microscopy, and impedance spectra indicate that BaFe(12)O(19) particles are isolated homogeneously by BaTiO(3) particles. In a 1.8 T magnetic field, a large room temperature magnetodielectric effect over 4.3% is observed in the 0.8BaTiO(3)–0.2BaFe(12)O(19) composite. The total mechanical energy dissipation (Q(–1)) for the BaTiO(3)–BaFe(12)O(19) composites was composed of the mechanical damping of BaFe(12)O(19), the mechanical damping of BaTiO(3), and the loss at the interface. The mechanical damping of BaFe(12)O(19) plays the dominant role in the variation of Q(–1).
