Structural and Electrical Characteristics of Bi(Fe0.95Y0.05)O3 Ceramic

Abstract

 In this work, studies of the structural and electrical characteristics of yttrium (Y) substituted bismuth ferrite (BiFeO₃) at Fe-site with a composition of Bi(Fe_0.95Y_0.05)O₃ (abbreviated as BFYO5) has been reported. BFYO5 material has been synthesized through a conventional solid state reaction method. The basic crystal data and phase formation were analyzed by using X-ray diffraction (XRD). Detailed studies of the effect of Y (5%) substitution on electrical properties of BiFeO₃ has been examined by using phase sensitive multimeter (PSM) in a wide range of temperature (25-350⁰C) and frequency (1-1000 kHz), which provided a significant enhancement in the electrical properties of bismuth ferrite. Our results confirmed that yttrium doped BiFeO₃ at Fe-site is an effective way to rectify various issues relevant for device applications.
