Ethanol-Assisted Hydrothermal Synthesis and Characterization of BiFeO3 Nanopowders

Well‐crystallized pure BiFeO3 nanopowders were successfully synthesized at the temperature as low as 120°C by an ethanol‐assisted hydrothermal process. In this synthesis, the composition of the solvent played important roles in the formation of pure BiFeO3. The BiFeO3 nanopowders synthesized with 4:...

Description
Summary:Well‐crystallized pure BiFeO3 nanopowders were successfully synthesized at the temperature as low as 120°C by an ethanol‐assisted hydrothermal process. In this synthesis, the composition of the solvent played important roles in the formation of pure BiFeO3. The BiFeO3 nanopowders synthesized with 4:3 ethanol/water ratio mainly consists of cubic structures with size from 50 to 150 nm. Zero‐field‐cooled (ZFC) and field‐cooled (FC) magnetization measurements indicated that pure BiFeO3 nanopowders showed a spin‐glass transition below the freezing temperature. Moreover, the BiFeO3 nanopowders exhibited ferromagnetic order at room temperature.
