Figure 4

Mn (a) and Cu (b) XAS (upper panel) and XMCD (lower panel) spectra in the TEY collection mode at 30 K in the remanent state (P), and at H=60 Oe (AP) after applying an opposite saturating field along the [100] direction. (c) X-ray resonant magnetic scattering Hysteresis loops at 30 K and 641.8 eV for the Mn L3-edge and at 947.8 eV for the Cu L2-edge for fields applied along the [100] direction. (d) The sketch illustrates the magnetic coupling through the induced Cu moment at the interface. Both Mn magnetizations point in different directions due to the different easy axis. Orbital reconstruction induces a moment in the Cu (orange arrows) sublattice aligned antiparallel to the top (red arrow) and bottom (blue arrow) Mn moments.
