Topology of the polarization field in ferroelectric nanowires from first principles
J. W. Hong, G. Catalan, D. N. Fang +2
The behaviour of the cross-sectional polarization field is explored for thin nanowires of barium titanate from first-principles calculations. Topological defects of different windi…
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…
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…
