Abstract = {{We present a study of Mn magnetic impurities (about 2%) in Ni with
   resonant x-ray emission spectroscopy excited at the L-2,L-3 edges of Mn
   using circularly polarized x rays incident almost parallel/antiparallel
   to the magnetization. The results are discussed jointly with absorption
   magnetic circular dichroism and complemented with elastic reflectivity
   measurements. Moreover, we show that emission spectroscopy is
   particularly suitable to the impurity problem, since the
   self-absorption/saturation corrections to the measurements are rather
   limited. The problem is treated also theoretically with a full multiplet
   splitting calculation of a single Mn2+ (3d(5)) ion with cubic crystal
   field. The theory reproduces satisfactorily all experimental trends of
   the features dispersing with the incident photon energy in the whole L-3
   region, whereas it is not adequate just below the L-2 excitation. The
   joint use of the theory and of the measurements allows us to extract the
   nondispersive component from the measured spectra. It is shown that this
   component does not correlate directly with the 3d-Mn local density of
   states. The general implications of the results are discussed.}},
