摘要：
Polycrystalline ceramics of SmBi3Ti3O12 were prepared by the solid state reaction method. Extensive impedance studies were carried out on these samples. From the measurements, it was observed, that low concentrations of a rare earth substituent for the bismuth site showed broad dielectric and impedance peaks. Ferroelectricity is observed in this material in the form of hysteresis between the polarization and electric field. The results are discussed.
