Fatigue problems were investigated for thin films of ferroelectric Bi-layered perovskite materials, that is, SrBi_2Ta_2O_9 and Bi_4Ti_3O_12. The bulk samples of the materials were sintered by solid reaction methods using constituent powders. Using the bulks as target materials, thin films were grown on various substrates by pulsed laser deposition methods. Many analytical methods were performed in order to find out the mechanism of imprint and fatigue problems in such thin films.
