Abstract
A novel series of polar ferroelectric Aurivillius oxides, containing Sc3+ in the B-site, were synthesized. The ferroelectric to paraelectric phase transition temperature (Tc) obtained from dielectric measurements range from 270−400 °C. Polarization vs electric field measurements on bulk samples revealed that remanent polarizations range from 10−12 μC/cm2, which are two times higher than that of the parent Bi2SrTa2O9.
