Abstract

A correlation between the ratio of the Fermi temperature T_F^* and the Debye temperature θ_D and the occurrence of superconductivity or magnetic order is described. Values of T_F^*/θ_D≫ 1 are found to favor "conventional" superconductivity, whereas T_F^*/θ_D≲ 1 favors magnetic order. "Heavy fermion" superconductivity is found to be restricted to the case T_F^*/θ_D < 1.
