Modulating Charge-Orbital Ordering in SmBaMn2O6 Single Crystals with Tuneable Strain.

ORAL

Abstract

SmBaMn2O6 is a perovskite manganese oxide with A-site ordering where competing interactions lead to a series of phase transitions. The observed orderings include charge-orbital-ordering, antiferromagnetic ordering, ferromagnetic canting and spin re-orientation. The Structural phase transition associated charge-orbital-ordering clearly indicate a strong relation between the lattice, charge and orbital. A systematic study with tunable strain along lattice directions is done to study how the latter two interact with lattice, as well as how the interplay contributes to the macroscopic properties.
