Abstract / Bemerkung
Recent experiments introducing controlled disorder into optimally doped cuprate superconductors by both electron irradiation and chemical substitution have found unusual behavior in the rate of suppression of the critical temperature T(c) vs increase in residual resistivity. We show here that the unexpected discovery that the rate of T(c) suppression vs resistivity is stronger for out of plane than for in plane impurities may be explained by consistent calculation of both T(c) and resistivity if the potential scattering is assumed to be nearly forward in nature. For realistic models of impurity potentials, we further show that significant deviations from the universal Abrikosov-Gor'kov T(c) suppression behavior may be expected for out of plane impurities.
