摘要

Abstract

Polycrystalline thin films ofstrontium bismuth tantalate Sr_yBi_{2 +} _xTa₂O₉ with different Sr : Bi : Ta molar ratios are obtained by a sol–gel method. The formation of a phase with a perovskite structure is established. Phase transitions are confirmed by dielectric spectroscopy. In the mode of polarization switching spectroscopy, remnant piezoelectric hysteresis loops are obtained which confirm the ferroelectric nature of the synthesized Sr_yBi_{2 +} _xTa₂O₉ films.
