| Abstract: | The strong coupling Schossmann–Schachinger theory for the upper critical field is considered methodically from the user point of view. We check the accuracy of approximate formulas for the upper critical field. In particular, we explain in detail how a convenient expression recently proposed by Shulga et al.(11) can be justified. The connection of Hc2(0) with the critical temperature Tc is considered and the similarity with the Allen–Dynes Tc-formula is shown explicitly. |
