| Abstract: | The scaling relation of single parameter scaling hypothesis is applied to the study of the scaling behavior of high temperature superconductors under pressure. The data of resistance and magnetization under various pressures are scaled onto a universal curve according to this scaling relation. The scaling parameters are pressure dependent while temperature independent. It is found that the controlling parameter B i equals the relative critical temperature t cP , which indicates that the superconducting energy gap at the zero temperature 2Δ s0 is the controlling parameter in this scaling. |
