Electronically phase separated nano-network in antiferromagnetic insulating LaMnO3/PrMnO3/CaMnO3 tricolor superlattice

Abstract

In strongly correlated materials multiple electronic phases can form simultaneously in real space, offering the potential of devices with multiple electronic properties, if such phase separation can be controlled. Here, Li et al study this electronic phase separation in LaMnO3/CaMnO3/PrMnO3 superlattice, and find a nano-network electronic phase separation resulting from local strain relaxation that persists through thermal cycling.
