Abstract

We observe an induced switchable magnetic moment of 1.6 ± 0.40 υ_{B/Fe in the nominally antiferromagnetic LaFeO}d3^/La_0.7Sr_0.3MnO₃/SrTiO₃(111). The magnetic reconstruction is driven by a mismatch of oxygen octahedra rotations resulting in an atomic reconstruction of reduced symmetry at the interface, reaching 1-5 layers into LaFeO₃. Density functional theory models a ferrimagnetic state at the interface. Together these results suggest that engineered oxygen octahedra rotations, affecting the local symmetry, affect electron correlations and can be used to promote novel magnetic properties.
