A multiferroic on the brink: uncovering the nuances of strain-induced transitions in BiFeO${}_3$

Daniel Sando, Bin Xu, Laurent Bellaiche +1

Bismuth ferrite (BiFeO${}_3$) is one of the very few known single-phase multiferroic materials. While the bulk compound is rhombohedral (R), the discovery of an epitaxial strain-indu…
