Abstract

Room temperature multiferroic properties, such as antiferromagnetism concurrent with ferroelectricity in Bismuth Ferrite (BiFeO₃), have triggered numerous investigations in its preparation and characterization. In this article, we report the modulation of multiferroic properties of high-density BiFeO₃ (BFO) ceramics sintered at temperatures between 625 °C and 825 °C using Spark Plasma Sintering (SPS). The highest density was obtained in samples sintered at 750 °C. XRD spectrum indicated that BiFeO₃ (BFO) sintered at 625 to 825 °C exhibited an R3c phase. Structural impurities as well as remanent and saturation magnetizations and coercive fields were unaffected in samples sintered at temperatures up to 750 °C, after both impurities and magnetizations increased while coercivity decreased beyond this temperature. During which a sharp increase was noted, reaching maximum values of approximately 0.05 emu/g for remanent magnetization and 1.37 emu/g for saturation magnetization. Additionally, BFO-750 exhibited higher remanent (P_r) and saturation (P_S) polarization, while BFO-800 showed an enhanced piezoelectric coefficient of approximately 6.32 pCN⁻¹ compared to other samples.
