Abstract
The xCoFe2O4-(1-x)PbZr0.52Ti0.48O3 (PZT) composite ceramics with x = 0.1, 0.2 and 0.3 have been prepared by solid state reaction method. X-ray diffraction result reveals that no chemical reaction or phase diffusion between the CoFe2O4 and PZT phases exists in the composites. The composites exhibited ferroelectric as well as magnetic characteristics at room temperature. The distribution of the ferroelectric and magnetic domains has been observed by Scanning Probe Microscopy (SPM). The dielectric properties of the composite ceramics were also investigated. The dependence of dielectric properties and the morphology of both the ferroelectric and magnetic domains on CoFe2O4 concentration were discussed in detail.
