Critical magnetic field in layered superconductors

The nature of the dependence Hc2(T) is greatly affected by the presence of magnetic impurities and their ordering at low temperatures. The scattering leads to a change in the sign of the curvature, and consequently to an increase in the value Hc2. The theory allows one to explain recent experimental data with the overdoped cuprates which exhibits behavior that is drastically different from the conventional picture. The calculations are in excellent agreement with the data.
