Abstract
In this study we report the effect of variations in the Sr/Bi ratio on the properties of thin film strontium bismuth tantalate (SBT), one of the primary candidates for ferroelectric nonvolatile memories. The composition was varied according to the formulation Sr1-zBi2.1+2/3zTa2O9. Films were prepared by pulsed laser ablation from ceramic targets. The largest switched polarizations were measured for compositions with z = 0. Results are compared to other studies where off-stoichiometric compositions yielded the largest polarizations. In attempting to reduce the processing temperatures, moderate ferroelectric properties were achieved at 650 °C.
