Abstract
Measurements of the irreversibility line H(T*) of Y1−xPrxBa2Cu3O6.97, a system in which the superconducting transition Tc can be varied from 0 to 92 K, show that H(T*) obeys a universal scaling relation characterized by an m=3/2 power law near Tc, with a crossover to a more rapid temperature dependence below T/Tc≊0.6. The applicability of the scaling formula to other high Tc superconductors is tested, with the results suggesting that both the crossover phenomenon and the power law temperature dependence are ubiquitous, scale-invariant properties of high temperature superconductors.
