Abstract

Lead iron tantalate Pb(Fe1/2Ta1/2)O3 (PFT) is a compound derived of general formula Pb(BIxBII1-x)O3 wherein x=1/2. In this work synthesis, sintering processes, dielectric, electrical, magnetic measurement, and Raman spectroscopy properties of PFT ceramics are described. The dielectric properties of PFT showed typical relaxor behaviors. We saw that ferroelectric and magnetic orders coexist in PFT at room temperature.
