(y) Li0.5Ni0.7Zn0.05Fe2O4+ (1-y) Ba0.5Sr0.5TiO3magnetoelectric composites with y = 0.1, 0.3 and 0.5 were prepared by a conventional standard double sintering ceramic technique. X-ray diffraction analysis confirmed the phase formation of ferrite, ferroelectric and their composites. logρdcVs 1/T graphs reveal that the dc resistivity decreases with increasing temperature exhibiting semiconductor behavior. The plots of logσacVs logω2are almost linear indicating that the conductivity increases with increase in frequency i.e. conductivity in the composites is due to small poloron hopping. Dielectric constant (έ) and dielectric loss (tan δ) were studied as a function of frequency in the range 100Hz–1MHz which reveal the normal dielectric behavior except the composite with y = 0.1and as a function of temperature at four fixed frequencies (i.e. 100Hz, 1KHz, 10KHz, 100KHz). ME voltage coefficient decreases with increase in ferrite content and was observed to be maximum of about 7.495 mV/cmOe for S1i.e. (0.1) Li0.5Ni0.7Zn0.05Fe2O4+ (0.9) Ba0.5Sr0.5TiO3composite.

Lead-free multiferroic magnetoelectric composites were prepared by incorporating the dispersed 0.4CoFe2O4ferromagnetic nanoparticles into 0.6(K0.5Na0.5)NbO3-LiSbO3ferroelectric micromatrix. From the x-ray diffraction analysis, it was observed that almost no chemical reaction occurs between the ferrite and the ferroelectric materials used to form the composite. Dielectric properties as a function of frequency were measured. The magnetoelectric couple effect was given as a function of magnetic field with a maximum magnetoelectric voltage coefficient of 15.01mV·cm-1·Oe-1at 1kHz, which was a very high value in the lead-free magnetoelectric composites system for the potential use on actuators and sensors, etc.
