The magnetoelectric composite with composition xCo0.8Ni0.2Fe2O4 + (1-x) Pb0.9925La0.005Zr0.55Ti0.45O3, x = 0.00, 0.05, 0.10, 0.15 and 1.00 were prepared by solid state reaction method. The structural, microstructural, dielectric, ferroelectric and magnetic properties were studied. The X-ray diffraction and Reitveld refinement of samples confirm the formation of mixed phases of tetragonal and cubic spinel structure in composite. The microstructure of composites shows the coexistence both types of grains corresponding to their phases. Frequency dependent dielectric studies at room temperature depict the decrease in dielectric constant (ε) and increase in tangent loss (tanδ) in composites with increase in ferrite content. P-E Hysteresis loop and M-H hysteresis loop confirms the ferroelectric and ferromagnetic nature of composites. Existence of P-E (ferroelectric) and MH (magnetic) at room temperature confirms the multiferroicity in the composites.
