The CeNi_4B compound is a mixed-valence system. It is a paramagnet with μ_{eff}= 0.52 μ_{B}/f.u. and the paramagnetic Curie temperature θ= -10.7 K. In the present research we complete our previous magnetic susceptibility and X-ray photoemission measurements with new studies by the X-ray magnetic circular dichroism method. The observation of the Ce M_{4,5} edges carried out with X-ray magnetic circular dichroism confirms the mixed-valence state deduced previously from X-ray photoemission spectroscopy. Moreover, we report on the measurements of the Ni L_{2,3} edges, which enable verification of the Ni contribution to the magnetism of this compound.
