| Abstract: | Abstract Highly oriented (Ba,La)Nb2O6 thin films have been synthesized by a chemical solution deposition method. A homogeneous and stable (Ba0.75La0.167)Nb2O6 (BLN) precursor solution was prepared by controlling the reaction of metal alkoxides. BLN precursor films crystallized in the tetragonal tungsten bronze phase at 700°C. BLN thin films on MgO(100) and Pt(100)/MgO(100) substrates showed the prominent c-axis preferred orientation. BLN thin films on Pt(100)/MgO(100) exhibited the diffuse phase transition depending upon the frequency. |
