Figure 5
(a) Scattering contrast image obtained as the difference between circular right and circular left helicities of the incoming light, for a given applied external magnetic field direction. The diffraction orders are labeled starting from the specular equal to 0. The rectangle shows the region of interest used for integrations in order to obtain (b) asymmetry ratios (I +-I -)/(I ++I -) expressed in % for the 1/2, 1 and 3/2 orders as a function of energy. For clarity the 1 and 3/2 orders were shifted by 0.2% and 0.4%, respectively.  [article HTML]
