Impurity Effects in the Hc2 Anisotropy of Cubic Superconductors

For cubic type II superconductors the Hc2 anisotropy is evaluated in the non‐local regime, i.e., for metals with moderate impurity content at arbitrary temperatures below Tc. In particular it is shown that the contributions of Hc2 anisotropy originating from anisotropic electron‐electron coupling and those resulting from Fermi surface anisotropies differ in their impurity and temperature dependences.
