Magnetic properties of LSCO (M)/LSMO (N)/LSCO (M) (M/N/M) heterostructures probed by X-ray magnetic circular dichroism (XMCD) in total electron yield mode. XMCD results for a 3/3/3 heterostructure measured at the a Mn L-edge and the b Cr L-edge at 15 K. Normalized applied magnetic field dependence of the XMCD signal measured at c the Mn L-edge and d the Cr L-edge for the 3/3/3 sample. e Temperature-dependent XMCD results for a 3/6/3 heterostructure at the Mn L-edge. f Comparison of the magnitude of temperature-dependent XMCD signal at the Mn and Cr L-edges in an 0.5 Tesla magnetic field applied in the plane of the sample for a 3/6/3 sample. The Cr data are multiplied by a factor of 5 for clarity
