%X Strontium barium niobate (SBN) thin films of good quality were deposited on Pt/Ti/SiO2/Si substrate using a polymeric resin containing metallic ions. Films were crystallized at different temperatures and for different duration of time. The structure of these films was studied using X-ray diffraction. The coexistence of SrNb2O6 (SN) and SBN was observed in films crystallized at 700 ˇăC. The amount of SN decreases when the crystallization time increases. Ferroelectric properties were determined for films crystallized at 700 ˇăC for 1 and 5 h. For SBN film crystallized at 700 ˇăC for 1 h, the remanent polarization (Pr) and the coercive field (Ec) were 2.6 muC/cm2 and 71.9 kV/cm, respectively. For the film crystallized at 700 ˇăC for 5 h these parameters were Pr = 1.1 muC/cm2 and Ec = 50.5 kV/cm.
