We have investigated the dielectric, ferroelectric and magnetic properties of 0.9PbZr0.52Ti0.48O3-0.1CoR0.02Fe1.98O4 (R = Sm, Y, and Pr) multiferroic composites. The PZT and rare-earth doped CFO powders were synthesized separately by sol–gel auto-combustion technique. The multiferroic composites were then synthesized by mixing the appropriate amount of individual phases using the conventional solid-state technique method. The powder X-ray diffraction technique showed that the PZT retains its tetragonal perovskite structure, while as rare-earth doped CFO possesses cubic spinel structure. Frequency and temperature dependent dielectric investigations of the multiferroic composites showed that in the lower frequency range, both ε' and tanδ decrease with increasing frequency but remain almost constant at higher frequencies, indicating normal dispersion behavior. The dielectric constant in the temperature range of 293–800 K clearly shows the ferroelectric phase transition corresponding to the PZT phase. All composites showed well M-H and P-E hysteresis loops, confirming their ferromagnetic and ferroelectric properties. The presence of rare-earth element in the ferrite phase of the composites results in change of magnetic and ferroelectric characteristics, thus showing that these properties can be tailored by doping rare-earth elements.
