Bi(2)CoO(2)F(4)—A Polar, Ferrimagnetic Aurivillius Oxide-Fluoride

[Image: see text] Aurivillius oxides have been a research focus due to their ferroelectric properties, but by replacing oxide ions by fluoride, divalent magnetic cations can be introduced, giving Bi(2)MO(2)F(4) (M = Fe, Co, and Ni). Our combined experimental and computational study on Bi(2)CoO(2)F(4...

description [Image: see text] Aurivillius oxides have been a research focus due to their ferroelectric properties, but by replacing oxide ions by fluoride, divalent magnetic cations can be introduced, giving Bi(2)MO(2)F(4) (M = Fe, Co, and Ni). Our combined experimental and computational study on Bi(2)CoO(2)F(4) indicates a low-temperature polar structure of P2(1)ab symmetry (analogous to ferroelectric Bi(2)WO(6)) and a ferrimagnetic ground state. These results highlight the potential of Aurivillius oxide-fluorides for multiferroic properties. Our research has also revealed some challenges associated with the reduced tendency for polar displacements in the more ionic fluoride-based systems.
