The deposition ratio (Ba : Na : Nb) of tungsten-bronze type thin film ferroelectrics depend on the sputtering conditions. The dielectric constant, dielectric loss factor are 889 and 0.029 at room temperature. The leakage current density is about 100 μ A/cm3 at 1MV/cm. The remanent polarization and coercive field are 2.39 μ C/cm2 and 87.33kV/cm, and the SHG coefficient d is about 2.51 × 10-13m/V, respectively.
