The Gap and the Upper Critical Field as Function of Doping for High- Cuprates

Figure 2

Upper critical field as function of doping. The continuous curve shows the results obtained with our model. The circles correspond to the Wang and Wen calculations [15] from SH; the right triangles correspond to the Ando et al. calculations [40] from resistive transport; the squares are obtained from the Nernst effect [31]. The dashed lines are results for Bi-based superconductors, the upper one for Bi2212 and the lower one for Bi2201 [32].
