Abstract
We have studied the crystal structure and magnetic susceptibility in single phase samples of high Tc RBa2Cu3Oz (where R = Y and Eu) systems in which all the four elements appearing in the formula unit were replaced by different dopants. The Tc for R = Eu is more sensitive to substitutions. When Ba or oxygen are replaced by K+ or sulfur Tc does not change for R = Y, yet, a progressive decrease in Tc is observed for R = Eu. Partial substitution of Pr for Y or Eu and Fe for Cu leads to the suppression of Tc in both systems, but a sharper decrease of Tc is observed in the case of R = Eu.
