Abstract

Pr_Ba and Pr_Sr are the defects responsible for the suppression of superconductivity in PrBa₂Cu₃O₇ and in Pr_1.5Ce_0.5Sr₂Cu₂NbO₁₀, respectively, and are difficult to detect with conventional techniques. Even neutron scattering has difficulty detecting Pr_Ba because the scattering lengths of Pr and Ba are so similar. In this paper, we point out how these alkaline-earth-site Pr defects can be readily detected indirectly in fully oxygenated samples, using measurements of the c-axis lengths.
