Abstract

By analyzing the pressure effects on the resistivity (ρ) of some high temperature superconductors, we have found a strong corelation between the normal state ρ and the superconducting transition temperature (T_c). Experimental data show that when pressure reduces the normal state ρ, T_c increases; when pressure enhances ρ, T_c decreases. Our experimental data can be explained in terms of the parabolic T_c-n (carrier concentration) function, suggesting that the pressure-induced variation of p arises from the change in n.
