At pressures Pup to 210 kbar the critical temperature vs pressure curves for the single crystal and ceramic samples of YBa2Cu307 _ y were found to be nonlinear in nature. The value of the derivative dTc /dP correlates with the value of Tc at Ρ = 0: For single crystals with lower values of Tc the value of dTc /dPi& higher.
