All doped BFO samples exhibit visible-light response, and the Co- and Ni-doped BFO samples present enhanced ferro-magnetic order at room temperature. All doped samples show secondary phases in minor quantities. Optical spectra reveal two absorptions bands, indicating multiple electron transitions for BFO and its secondary phases. M − H hysteresis loops suggest enhanced ferromagnetism in the Co- and Ni-doped BFO samples because of magnetic spinel CFP and NFO phases, respectively, whereas changes in oxygen vacancies and Fe–O–Fe bond angle play minor roles in the ferromagnetic behavior.en-USrestritoPowders: solid-state reactionMagnetic propertiesFerritesArtigo publicado em periodicohttps://www.sciencedirect.com/science/article/pii/S0272884221015765https://doi.org/10.1016/j.ceramint.2021.05.176
