(a) Schematic drawing of XRMS from a multilayered circular dot array. (b) Hysteresis loops of field-dependent XRMS intensities measured at the Fe and Co absorption edges.
(a) Hysteresis loops and (b) magnetic configurations of the NiFe (top) and Co (bottom) layers obtained from micromagnetic simulations. The (H, ) positions corresponding to each configurations in (b) are marked as the symbols in (a). Large arrows in yellow indicate the applied field direction.
Remanent curves (solid lines) measured from XRMS intensities (a),(b) and calculated by micromagnetic simulations (c),(d). The dotted lines show the major hysteresis loops. The simulated and measured loops show two regions (labeled A and B) where the magnetic domain structures are stable.
Micromagnetic configurations from micromagnetic simulations are shown for the three regions O, A, and B as indicated in Fig. 3.
