摘要：

Composite thin films produced by depositing alternating layers of various PLZT compositions were fabricated on Pt-coated Si wafer and Ag foil substrates. Films were prepared by MOD processes including automatic spin and dip coating from acetate precursors followed by annealing at 700 degrees C. Ferroelectric (FE)/ antiferroelectric (AFE), FE/relaxor and relaxor/AFE composites consisted of individual layer compositions including ferroelectric PLZT 2/55/45 and 7/65/35; AFE PLZT 0/100/0, 0/96/4 and 0/95/5; relaxor PLZT 9.5/65/35 and 12/65/35. The structural and electrical properties of the composite films were investigated. Composites were developed with 1) improved AFE-to-FE domain switching with decreased AFE-to-FE transition field and increased saturation polarization for materials with AFE-type properties, 2) increased induced polarization with decreased coercivity and polarization remanence for relaxor-type composites and 3) increased hysteresis loop squareness for ferroelectric memory materials compared with films of homogeneous PLZT composition.
