Ferroelectric oxides with low bandgaps are mainly based on the BiFeO perovskite upon the partial substitution of iron with different cations. However, the structural stability of many of these perovskites is only possible by their processing at high pressures (HP, >1GPa) and high temperatures (HT, >700ºC). [...]
