(a) XAS and (b) XMCD image at705.8 eV. The field of view is 30 μm. (c) XMCD image recorded in remanence showing the magnetization pattern of the same crystal presented in Fig. 2(a). The field of view is 4 μm. The inset shows the experimental geometry. (d) (Top) XAS spectrum from the magnetite crystal. (Bottom) XMCD difference spectrum. The inset shows a typical XMCD spectra from stoichiometric magnetite.
