• Ferroelectric characteristics of (Bi,La)4Ti3O12 (BLT) and SrBi2Ta2O9 (SBT) films were changed by addition of certain silicates and germanates. The ferroelectric films were formed by spin-coating mixed chemical solution of BLT or SBT and silicate or germanate on a Pt/Ti/SiO2/Si structure. In the BLT-based films, it was found from X-ray diffraction (XRD) analysis that the preferred orientation of crystallites was changed by changing metal elements in the silicates and germanates. From $P$–$V$ (polarization vs. voltage) measurement, it is evident that the remanent polarization and coercive field were changed reflecting these different orientations. On the other hand, the crystallite orientation of the SBT-based films did not change, although its remanent polarization and coercive field were changed by additives.
