TL;DR: In this article, the impurity-scattering rate of pure and Zn-doped d-wave superconductors under magnetic field was estimated. And the authors showed that the ''plateau'' in the ''ensuremath{\kappa}(H)$ profile is not observed in the majority of their Bi-2212 crystals, including one of the cleanest crystals.
