Abstract

La0.67Sr0.33MnO3 (LSMO)/Pb0.92La0.08Zr0.65Ti0.35O3 (PLZT) composite film was fabricated on a (001) LaAlO3 (LAO) single crystal substrate by a sol-gel technique. The results from X-ray diffraction (XRD) indicated that LSMO and PLZT could grow successively on LAO substrate with (001) preferred orientation. The ferroelectric and ferromagnetic properties of LAO/LSMO/PLZT composite film were also investigated. The results showed that the remnant polarization Pr, and coercive field Ec of the composite film at room temperature were 36.38 μC/cm2 and 512.43 kV/cm respectively. Moreover, the composite film exhibited significant ferromagnetic hysteresis loops and soft magnetic behavior at temperatures lower than 250 K.
