Ty. Koo et al., THE STRUCTURE AND MAGNETOTRANSPORT PROPERTIES OF (PZT,LCMO) BILAYER FILMS, Journal of the Korean Physical Society, 29, 1996, pp. 612-615
Growth of bilayered thin films of ferroelectric PbZr0.52Ti0.48O3 and f
erromagnetic 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 p
olarization on the magnetoresistance (electromagnetotransport effect)
of La0.7Ca0.3MnO3 thin films are discussed. It is seen that the electr
ic field due to the ferroelectric polarization completely suppresses t
he sharp peak in magnetoresistance near the ferromagnetic transition p
oint.
