The effect of a Pb(Zr@sub 0.52@Ti@sub 0.48@)O@sub 3@ (PZT) buffer layer on a perovskite Pb(Zr,Ti)O@sub 3@-Pb(Mn,W,Sb,Nb)O@sub 3@ (PMWSN) thin film deposited on a Pt/Ti/SiO@sub 2@/Si substrate was examined. The film having stoichiometric PMWSN composition was deposited directly on the Pt/Ti/SiO@sub 2@/Si substrate by pulsed laser deposition. While as-grown PZT-PMWSN thin films have poor fatigue resistance, PZT-PMWSN thin films with PZT buffer exhibit good fatigue resistance. The insertion of PZT buffer layer contributes to enhance the crystallinity of PZT-PMWSN and it can protect to diffuse the accumulated charges at the interfaces between electrodes and the films.
