Resumen:
We present structural data refined from X-ray spectra for R1-xPrxBa2Cu3O7-δ (R=Er, Gd, Eu, Sm, Nd) systems with x=0, 0.1, and 0.4. The evolution of Tc with the ionic radius of the rare earth for different values of x can be related to the Cu2O4 distance. The effect of chemical pressure on Tc in R1-xPrxBa2Cu3O7-δ systems is opp osite to that of hydrostatic pressure on the Y1-xPrxBa2Cu3O7-δ system. © 1991.
