Abstract: Bi4Ti3O12 (BiT), Bi3.25La0.75Ti3O12 (BLT), Bi4-x/3Ti3-xNbxO12 (BTN) and Bi3.25-x/3La0.75Ti3-xNbxO12 (BLTN) thin films have been prepared by pulsed laser deposition. BTN and BLTN films exhibit a maximum in the remanent polarization P-r at a Nb content x = 0.018. At this Nb content, the BLTN film has a P-r value (25 muC/cm(2)) that is much higher than that of BiT and a coercive field (E-c = 120 kV/cm) similar to that of BiT. The polarization of this BLTN film is fatigue-free up to 10(9) switching cycles. The high fatigue resistance is mainly due to the substitution of Bi-3+ ions by La3+ ions at the A site and the enhanced P-r arises largely from the replacement of Ti4+ ions by Nb5+ ions at the B site. The mechanisms behind the effects of the substitution at the two sites are discussed.
