Phys. Rev. Lett. 106, 147205 (2011). https://doi.org/10.1103/PhysRevLett.106.1472050031-900710.1103/PhysRevLett.106.147205https://hdl.handle.net/20.500.14352/91184We report on the magnetic coupling of La0.7Sr0.3MnO3 layers through SrTiO3 spacers in La0.7Sr0.3MnO3/SrTiO3 epitaxial heterostructures. Combined aberration-corrected microscopy and electron-energy-loss spectroscopy evidence charge transfer to the empty conduction band of the titanate. Ti d electrons interact via superexchange with Mn, giving rise to a Ti magnetic moment as demonstrated by x-ray magnetic circular dichroism. This induced magnetic moment in the SrTiO3 controls the bulk magnetic and transport properties of the superlattices when the titanate layer thickness is below 1 nm.engjournal article1079-7114https://doi.org/10.1103/PhysRevLett.106.147205https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.106.147205restricted access539ManganitesComplex OxidesInterfacesFísica de materiales2211.17 Propiedades Magnéticas
