We substitute a few parts per million of 57Co for Ni. The Mössbauer spectra of HoNi2(57Co)B2C reveal the presence of two components, one of which is truly metallic as indicated by delocalization of 3d electrons. In the other component, the electrons are delocalized to a lesser extent. The relative ratio of the components can vary from sample to sample.
