Impurity-induced Tc reduction in high-temperature superconductors

Impurity-induced Tc reduction in high-temperature superconductors

We study the effects of nonmagnetic impurities substituted for Cu atoms on the superconducting transition temperature Tc in high-temperature cuprate superconductors, using the d-p model within the fluctuation exchange approximation and the coherent potential approximation. Tc near the optimum-doped...
