Bi3.25Eu0.75Ti3O12 (BET) thin films with various excess bismuth (Bi) contents (5, 10, 15, 20-mol%) were grown by a metal-organic decomposition method at 700 °C. Effects of excess Bi content on microstructure and electric properties of BET thin films were investigated. BET thin film with 10-mol% excess Bi content shows larger remnant polarization (66.3 C/cm2), better fatigue endurance (3% loss of 2Pr after 1.8×1010 switching cycles), and lower leakage current density (1×10-7 A/cm2) than those of other prepared BET thin films. Additionally, the mechanisms concerning the dependence of the properties on excess Bi content of BET thin films were discussed.

We have studied the strong hole self-doping into LaMnO3(LMO) thin films produced by metal organic decomposition (MOD) method. With different heat treatment conditions, LMO thin films have been prepared by the MOD method in the 100 % O2gas atmosphere. We consider that the excess of O2-ions in LMO thin films induces the strong hole self-doping into LMO ones. The quantity of excess O2-ions in LMO is sensitive to the heat treatment conditions of the LMO production, especially the temperature, time and atmosphere gas. Although LMO single crystal is an antiferromagnetic insulator, LMO thin films we have produced in the 100 % O2gas atmosphere by use of the MOD method shows the properties of ferromagnetic metal.
