Abstract. Ceramic composite materials based on compounds of lead zirconate-titanate and cobalt ferrite with different content of the initial components mass fraction have been synthesized. Using a complex of physicochemical methods, the microstructure and magnetodielectric properties of the synthesized ceramics have been studied. The resulting frequency dependences of the magneto-dielectric coefficient for the composite system (1-x)PZT + xCF(0.0 ≤ x ≤ 0.5) in an external magnetic field have a resonance form in the entire concentration range investigated. The largest changes in the value of the complex permittivity are observed for the sample with the composition of 0.6PZT + 0.4CF.

Key words: heterogeneous multiferroics, composites, lead zirconate-titanate, cobalt ferrite, dielectric and magnetic properties.
