Abstract

We have studied the crystal structure and magnetic susceptibility in single phase samples of high T_c RBa₂Cu₃O_z (where R = Y and Eu) systems in which all the four elements appearing in the formula unit were replaced by different dopants. The T_c for R = Eu is more sensitive to substitutions. When Ba or oxygen are replaced by K⁺ or sulfur T_c does not change for R = Y, yet, a progressive decrease in T_c is observed for R = Eu. Partial substitution of Pr for Y or Eu and Fe for Cu leads to the suppression of T_c in both systems, but a sharper decrease of T_c is observed in the case of R = Eu.
