Magnetic couplings vs. stress and strain in epitaxial (La, Sr)MnO3

Abstract

Based on ab initio calculations, we quantify the magnetic couplings and the stress tensor in ferromagnetic Sr-doped LaMnO3 upon combined application of built-in epitaxial and external uniaxial strains. We suggest YAlO3 as a substrate suited to change magnetic order in manganite film with practicable external strains. The effect could lead to strain-activated switches based on piezoelectric-piezomagnetic heterojunctions.
