Abstract

The results in this letter show the possibility of realizing a high magnetoelectric (ME) coefficient material by synthesizing the particulate composites of ferroelectric and ferromagnetic components using the annealing and aging treatment. The ME composites were fabricated using a combination of conventional mixed oxide sintering and thermal treatment. The thermal treatment constituted of annealing at temperature closer to calcination temperature (∼800°C) followed by aging at lower temperatures (300-400°C). Microstructure of the fabricated samples was analyzed using the X-ray mapping in scanning electron microscopy (SEM) and it was found that NiFe _1.9Mn_0.1O₄ (NFM) is distributed inside the Pb(Zr_0.52Ti_0.48)O₃ (PZT) grains on the length scales of 100nm. The magnitude of piezoelectric constant (d₃₃) and the dielectric constant exhibited significant variation with aging time and temperature. It was found that the magnitude of ME coefficient for PZT-5NFM sample increased from 37 to SomV/cm·Oe after thermal treatment, an enhancement of ∼50%.
