Abstract: The magnetic moment of the Mn impurities was obtained from magnetization measurements of Y ( Ni 1 - x Mn x ) 2 B 2 C as a function of the concentration x less than 0.15. Using the coherent potential approximation and starting from 3 d density of states, obtained from the first principles calculations, the magnetic moments are obtained within a two sublattice model. For adequately estimated values of the Coulomb interactions U, the position of the energy level of Mn and adopting values for the intersublattice hybridization term, a qualitative agreement with the observed experimental data is obtained.
