Periodicity-dependence of the ferroelectric properties in BiFeO3/SrTiO3 multiferroic superlattices

R. Ranjith, B. Kundys, W. Prellier

Artificial superlattices of (BiFeO3)m(SrTiO3)m (m= 1 to 10 unit cells) consisting of multiferroic BiFeO3 and insulating SrTiO3 layers were fabricated on (100)-oriented SrTiO3 subst…
