Abstract: The influence of an external pressure on the behavior of the spin-gap temperature observed in the de resistivity is measured on Y1-xPrxBa2Cu3O7 films with x=0.2, 0.3, and 0.4 and an oxygen-deficient YBaxCu3Oy film with y=6.6. It is found that the spin-gap temperature shifts with pressure in a sense opposite to the shift of the critical temperature, consistent with the resonating valence bond mean-field phase diagram. The modified carrier density induced by the pressure is the major effect, while no significant effect of enhanced interplane-coupling of the Cu2+ spins due to a decrease in the distance between the CuO2 planes is observed.
