PROPERTIES OF SUPERCONDUCTING ALLOYS CONTAINING PARAMAGNETIC IMPURITIES,
Abstract
Calculations were made on the effects of paramagnetic impurities in superconductors using the Abrikosov-Gor'kov theory as our starting point and taking full advantage of the information contained in the Green's function of the system. The density of states in energy was computed for different values of the inverse collision time for exchange scattering. These calculations show clearly that the essential feature of superconductivity is the correlation of the electrons rather than the existence of a gap in the excitation energy spectrum. For even in the absence of a gap, so long as correlations persist there is an ordered state below a certain critical temperature which displays the usual properties of a superconductor.
