Abstract

The trio of ruthenate compounds, doped Sr₂YRuO₆, GdSr₂Cu₂RuO₈, and Gd_2−zCe_zSr₂Cu₂RuO₁₀ all superconduct in their SrO layers, which is why they have almost the same ≈49 K onset temperatures for superconductivity. The sister compound Ba₂GdRuO₆, whether doped or not, does not superconduct, because the Gd breaks Cooper pairs. These fit in with the superconducting cuprates: the superconducting layers are SrO or BaO, not CuO₂.
