Abstract

Dielectric properties of xBaTiO3–(1-x)CoFe2O4 composite materials have been investigated. Dielectric properties of BaTiO3, CoFe2O4 and 0.5BaTiO3–0.5CoFe2O4 samples show frequency dependence, which is classified as relaxor behavior with different relaxing degree. The relaxor behaviors were described using the modified Curier-Weiss and Vogel–Fulcher laws. Among three above samples, the BaTiO3 sample has highest relaxing degree. Photoluminescence spectral indicated defects, which might in turn control relaxing degree.
