Induced Ti magnetism at titanate / manganite interfaces

ORAL

Abstract

We show evidence of induced magnetism resulting from the electronic (charge) or orbital reconstruction occurring at the interface. We show a novel form of Ti magnetism at the interface between SrTiO$_{3}$ (STO) and LaMnO$_{3}$ (LMO) [1] as evidenced by evidenced by a strong XMCD signals at Ti and Mn edges. The magnetic alignment (ferromagnetic or antiferromagnetic) of Ti and Mn moments can be tuned by structural parameters. \\[4pt] [1] J. Garcia-Barriocanal et al.
