摘要：

We present structural data refined from X-ray spectra for R1-xPrxBa2Cu3O7-delta (R = Er, Gd, Eu, Sm, Nd) systems with x = 0, 0.1, and 0.4. The evolution of T(c) with the ionic radius of the rare earth for different values of x can be related to the Cu2-O4 distance. The effect of chemical pressure on T(c) in R1-xPrxBa2Cu3O7-delta systems is opposite to that of hydrostatic pressure on the Y1-xPrxBa2Cu3O7-delta system.
