Metal-insulator transition in $(LaMn{O}_3{)}_{2n}/(SrMn{O}_3{)}_n$ superlattices

Abstract

The modulation of charge density and spin order in (LaMnO${}_3$)${}_{2n}$/(SrMnO${}_3$)${}_n$ ($n$=1-4) superlattices is studied via Monte Carlo simulations of the double-exchange model. G-type antiferromagnetic barriers in the SrMnO${}_3$ regions with low charge density are found to separate ferromagnetic LaMnO${}_3$ layers with high charge density. The recently experimentally observed metal-insulator transition with increasing $n$ is reproduced in our studies, and $n=3$ is found to be the critical value.
