Interfacial Control of Magnetic Properties at LaMnO3/LaNiO3 heterostructures
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.
Reduction of Mn19 Coordination Clusters on a Gold Surface
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.
Control of Tc in La0.7Sr0.3MnO3 via piezostrain
X-ray magnetic circular dichroism measurements evidence a 10K shift of the magnetic Curie temperature for La0.7Sr0.3MnO3 deposited on the piezoelectric substrate [Pb(Mg1/3Nb2/3)O3]0.68−[PbTiO3]0.32 (011) for two different remanent piezostrain states.
