Combined electrostatic and strain engineering of BiFeO${}_3$ thin films at the morphotropic phase boundary

Johanna Nordlander, Bastien F. Grosso, Marta D. Rossell +5

Multiferroic BiFeO${}_3$ (BFO) possesses a rich phase diagram that allows strain tuning of its properties in thin-film form. In particular, at large compressive strain, a supertetrag…
