Effect of stacking order on the magnetic and transport properties of bilayer-based oxide superlattices with inversion symmetry

SrRuO3 - SrMnO3 multilayers with heterointerfaces of similar inversion symmetry were fabricated. The SrTiO3 / [SrMnO 3 / SrRuO3]15 multilayer shows lower Curie temperature, smaller magnetization and larger magnetoresistance compared to SrTiO3 / [SrRuO3 / SrMnO3]15 multilayer. The variations of these properties with the inversion of stacking order are well correlated with each other which occur due to pinned/biased moments and can be explained by their cumulative stress difference. © 2009 American Institute of Physics.
