Yn. Ovchinnikov et Vz. Kresin, CRITICAL-FIELD AND IMPURITY SCATTERING - APPLICATION TO LAYERED AND 3D SUPERCONDUCTING SYSTEMS, Journal of superconductivity, 10(3), 1997, pp. 257-263
An efficient and rigorous method of evaluating the critical field H-c2
is developed. The method allows one to consider in a regular way the
angular dependence of the scattering cross-section. The method is appl
ied to layered and 3D superconductors.
