Using a X-ray magnetic circular dichroism measured at the X-Treme beamline, SLS, in conjunction with X-ray reflectivity measured at the SEXTANTS beamline, SOLEIL, the authors show that the degree of intermixing at the monolayer scale allows interface-driven properties such as charge transfer and the induced magnetic moment in the nickelate layer to be controlled.

The surface-induced changes of the oxidation state and magnetic properties of Mn ion clusters have been probed by X-ray absorption spectroscopy and X-ray magnetic circular dichroism.

X-ray magnetic circular dichroism measurements evidence a 10K shift of the magnetic Curie temperature for La_0.7Sr_0.3MnO₃ deposited on the piezoelectric substrate [Pb(Mg_1/3Nb_2/3)O₃]_0.68−[PbTiO₃]_0.32 (011) for two different remanent piezostrain states.
