Determining the upper magnetic critical field in YBCO films

In the quest to increase the critical temperature of superconductors, it is essential to identify the factors that limit the strength of superconductivity. The upper critical field Hc,2 is a fundamental measure of that strength. Only in recent years, its magnitude and doping dependence has been measured in cuprate superconductors, but only when they areContinue reading “Determining the upper magnetic critical field in YBCO films”
