Figure 3: Soft X-ray reflectivity at the Mn L3-edge of the (LNO7/LMO7)15 superlattice at 30 K and in 0.05 T after cooling in the same field.
From: Interlayer coupling through a dimensionality-induced magnetic state
(a) Reflectivities for circularly left (CL, blue line) and right (CR, red line) polarized light. Inset: extracted asymmetry ratio (CR−CL)/(CR+CL). (b) Reflectivity with linearly vertical (LV) polarized light. For simplicity, linear horizontal polarization is not shown. In all reflectivity curves, points are experimental measurements and solid lines are fits. Inset: corresponding Mn L2,3 X-ray absorption spectra. The arrow in the lower inset indicates the energy at which reflectivity measurements were performed. (c) Schematics of the scattering geometry for reflectivity measurements. (d) Sketch of the extracted magnetic configuration showing that the doubling of the magnetic structure along the normal direction corresponds to two LMO sublattices with their net magnetic moments oriented at 160° from each other.
