DOI: 10.1002/aelm.201500372 superlattices, in particular the (LaMnO3)m/ (SrMnO3)n system, has yielded important insights into the relationships between charge transfer, electronic structure, cation disorder, and magnetic ordering.[11–15] Ferroelectric superlattices have also received considerable attention,[16–18] with short-period superlattices emerging as a platform in which to realize improp...
