Abstract
Structural and superconducting properties of Y (Ni(1-x)M(x))(2)B2C com pounds with M=Co, Fe and Ru have been studied. A fast decrease of T-c with the concentration of the dopants was found. This effect can be at tributed to the shift of the Fermi level induced by the dopant concent ration with the additional contributions from the chemical-pressure ef fects and from the decrease of the electronic mean free path.
