Abstract
The presented DFT+<italic>U</italic> calculations revealed that the doping of BiFeO<sub>3</sub> with Al and Ga reduced the energy barrier between <italic>R</italic>3<italic>c</italic>-G and <italic>Cm</italic>-C phases whereas for Sc and In the energy difference between both phases increased.
