The beta to gamma (insulator-metal) transition in BiFeO3
Donna C. Arnold, Kevin S. Knight, Gustau Catalan +4
High temperature powder neutron diffraction experiments have been conducted around the reported beta-gamma, insulator-metal phase transition (~ 930 C) in BiFeO3. The results demons…
Effect of Chemical Pressure on the Magnetic Transition of Multiferroic Ca-BiFeO3
G. Catalan, K. Sardar, N. S. Church +3
Multiferroic BiFeO3 ceramics have been doped with Ca. The smaller ionic size of Ca compared with Bi means that doping acts as a proxy for hydrostatic pressure, at a rate of 1%Ca=0.…
Structural Origin of the Metal-Insulator Transition of Multiferroic BiFeO3
S. A. T. Redfern, J. N. Walsh, S. M. Clark +2
We report X-ray structural studies of the metal-insulator phase transition in bismuth ferrite, BiFeO3, both as a function of temperature and of pressure (931 oC at atmospheric pres…
