The beta to gamma (insulator-metal) transition in BiFeO3
The beta to gamma (insulator-metal) transition in BiFeO3
High temperature powder neutron diffraction experiments have been conducted around the reported beta-gamma, insulator-metal phase transition (~ 930 C) in BiFeO3. The results demonstrate that while a small volume contraction is observed at the transition temperature, consistent with an insulator-metal transition, both the beta and gamma phase of BiFeO3 exhibit …
