Abstract
The transition temperature of Nb as a function of the concentration of such paramagnetic impurities as Fe, Ni, and Co shows a very strong anomaly close to the critical concentration which destroys superconductivity. The strength of the effect in Nb is believed to be caused both by the weak depairing of the impurities and by their nonstatistical distribution resulting from the layered structure.
