M. Sacchi et al., MAGNETIC EFFECTS ON THE RESONANT X-RAY REFLECTIVITY - CIRCULAR-DICHROISM AT THE 2P EDGES OF NI, Journal of magnetism and magnetic materials, 147(1-2), 1995, pp. 11-15
We measured the X-ray reflectivity of a Ni(110) crystal over the photo
n energy range including the 2p absorption edges of Ni. Using circular
ly polarized X-rays, we observed large variations in the resonant refl
ectivity according to the relative orientation between sample magnetiz
ation and photon helicity. The angular dependence of the dichroism and
the use of resonant magnetic reflectivity for drawing hysteresis curv
es are also discussed.
