Giant Magnetoelectric Effect in PZT Thin Film Deposited on Nickel

Abstract

Abstract The magnetoelectric (ME) effect has been investigated in lead zirconate titanate (PZT) thin film deposited on nickel foil using chemical solution deposition (CSD) technique. The synthesized PZT thin films are found to possess perovskite structure without presence of any intermediate layer. PZT thin film deposited on nickel foil exhibits a good ferroelectric property with a high remnant polarization of about 86 µC/cm 2 .The ferroelectric loop has been modeled using domain wall theory to verify the behavior of the ferroelectric domains. It is observed that deposition conditions, specially annealing temperature, play a crucial role in enhancing the magnetoelectric effect. A high ME coefficient of 220 mVcm –1 Oe –1 at a bias magnetic field of 50 Oe has been obtained due to enhanced magnetoelectric coupling between PZT film and nickel foil.
