Electrical and Magnetic Properties of Multiferroic BiFeO₃ Ceramics Prepared Using Sol-Gel Derived Fine Powders

Article Preview

Abstract:

Insulating BiFeO₃ ceramics with a small amount of secondary phase Bi₂Fe₄O₉ were prepared by rapid sintering at 840 °C using sol-gel derived fine powders. The ceramics are dense and consist of grains of 3∼8 μm in size. Their leakage current density remains lower than 5.5×10⁻⁵ A/cm² under the applied electrical field below 100 kV/cm. The main conduction mechanism from 50−190 kV/cm is space-charge-limited-current relating to oxygen vacancies. The ceramics exhibit a saturated ferroelectric hysteresis loop with a remanent polarization (2P_r = 22 μC/cm²) under the applied field of 165 kV/cm. Weak ferromagnetism was observed with a remanent magnetization 2M_r of 1.2×10⁻⁴ μ_B/Fe at 300 K and of 1.8×10⁻⁴ μ_B/Fe at 10 K.
