Figure 5

Hysteresis curves (multiplied by −1) of the Co atoms (blue), Ni atoms (green) and Fe atoms (grey) obtained at the L2,3 edges XMCD maxima at T=2 K, and θ=45°. (Monochromatized X-rays are set at the energy of the maximum absolute value of the XMCD signal (that is, hν=777.5 eV for Co, hν=851 eV for Ni, and hν=707 eV for Fe) then the external magnetic field is switched step by step from +6.5 T down to −6.5 T and back to +6.5 T. At each step the magnetic field is switched from left to right circular polarization to yield the element specific magnetization curves.
