Abstract
Magnetoelectric composites of Ni 0.8 Co 0.1 Cu 0.1 Fe 2 O 4 and Lead Zirconate Titanate (PZT) were prepared by using conventional ceramic method. The measured values of saturation magnetization ( M s ) and magnetic moments ( μ B ) are in accordance with the volume fraction of ferrite content in the composite. The dielectric constant of the composites decreases with frequency. The plots of dielectric constant ( ε r ′ ) against temperature ( T ) show a peak at their respective transition temperatures. The ME output was measured by varying dc bias magnetic field. A large ME output signal of 776 mV/cm was observed for 35% ferrite +65% ferroelectric composite. The magnetoelectric (ME) response is found to be dependent on the content of ferrite phase.
