摘要：

The complex dielectric response of tungsten bronze Sr1-xBaxNb2O6 [SBN(1-x)/x, x=0.40, 0.50 and 0.60] relaxer ferroelectric ceramics was carefully studied as a function of temperature between -180 degrees C and 450 degrees C. Three distinct relaxation features were observed in all the compositions. The thermal hysteresis of dielectric maximum was considered to be associated with "lock in" of the incommensurate phase. It was confirmed by investigation of the Curie-Weisis behavior at a higher temperature range. These results were also discussed in terms of the polarization fluctuation of polar microregions briefly.
