Abstract

PbZr_xTi_1-zO₃(PZT)/La_1-xSr _xCoO₃(LSCO) heterostructures were grown on MgO(100) substrates using the sol - gel technique and their structural and electrical properties were investigated. X-ray diffraction analysis showed that the PZT/LSCO film was polycrystalline with partial preferred (001/100) orientations. Fairly good ferroelectric properties of PZT were obtained when the PZT films were deposited on a well-crystallized LSCO film and were annealed at 700°C for 1 min. A typical value of the remnant polarization was 28 μC/cm². It was also found that a longer annealing time enhanced the interdiffusion of constituent elements between LSCO and PZT. It is concluded from these results that in sol - gel processing, prevention of interdiffusion and crystallinity of the LSCO electrode film are two important factors for obtaining the desirable structural and electrical properties in this system.
