Measured specular reflectivity curve (symbols) along with the fit (sold line). The incident x-ray energy was 6.533 keV. (Insets) Schematic representation of scattering geometry for XRMS measurement and reflectivity curves measured at 639 and 641 eV with soft x rays.
[(a)–(c)] Sum and difference of reflected intensities for opposite polarizations, measured at three different incident angles across the Mn L edges. Measured specular reflectivity curves (symbols) along with fits (sold lines) in arbitrary units. (d) Extracted charge (fc) and magnetic (fm) scattering factors for Mn atoms in electron units.
Measured (symbols) and fitted (sold lines) magnetic field dependencies of the difference signals at 60 K. In each plot, two numbers indicate the x-ray incident angle and energy, the number in parenthesis represents the x-ray penetration depth, and arrows indicate field sweeping directions.
(a) Net moment from the entire sample obtained from SQUID measurement and XRMS calculation. (b) Calculated projected moment of each of top five LBMO layers . Arrows indicate field sweeping directions.
