The structure and magnetotransport properties of (PZT,LCMO) bilayer films

Abstract

Growth of bilayered thin films of ferroelectric PbZr0.52Ti0.48O3 and ferromagnetic La0.7Ca0.3MnO3 on MgO(100) substrates by the pulsed laser deposition is reported. Resistance and magnetoresistance measurements of the bilayered films were performed. The effects of ferroelectric polarization on the magnetoresistance (electromagnetotransport effect) of La0.7Ca0.3MnO3 thin films are discussed. It is seen that the electric field due to the ferroelectric polarization completely suppresses the sharp peak in magnetoresistance near the ferromagnetic transition point.
