摘要：
Ba2NaNb5O15 (BNN) thin films were deposited by the If magnetron sputtering method on fused-quartz and Pt substrates in Ar+O-2 (9:1) atmosphere at 2Pa for 8h. The c-axis-orientated BNN thin films were successfully grown at the substrate temperature of 730 degrees C and 780 degrees C. The remanent polarization (Pr) and coercive field (E(c)) of specimen deposited at 730 degrees C were 30.9 mu C/cm(2) and 13kV/cm, respectively. The second harmonic generation (SHG) experiment was performed using Nd:YAG laser (lambda=1.06mm). The SHG intensity of specimen deposited at 830 degrees C was the strongest compared with another two specimens deposited at 730 degrees C and 780 degrees C.
