Effect of A-site ordering on the magnetoelectric properties in (111)-oriented LaMnO$_{3}$/SrMnO$_{3}$ superlattices

It is expected that the chemical order that occurs over the crystallographic A-sites might strongly influence the distribution of the charges, magnetic and transport properties of the perovskite magnates. In this work, we focus on growing LaMnO$_{3}$/SrMnO$_{3}$ superlattices on (111)-oriented by PLD. The superlattices were characterized by magnetic as well as electronic transport measurements, and compared with the La$_{2/3}$Sr$_{1/3}$MnO$_{3}$ thin film having the same components in which the A-site dopants are randomly distributed. The superlattices had different properties from the thin film: higher Curie temperature of FM and metal-insulator transitions, larger magnetization, and lower resistivity. This will allow for an understanding of the dependence of the intrinsic properties with respect to the long-range ordering of dopants. These differences can be explained by Mn$^{3+}$/Mn$^{4+}$ double exchange separation arising from the artificially induced the order of the A-site cations in the superlattices. Our proposed superlattices will allow for understanding of the fundamental magnetic and electronic interactions arising from dopant ordering in transition metal oxides.
