Sr2Cu2RuO10, GdSr2Cu2RuO8, and doped Sr2YRuO6, all superconduct in their SrO layers, which is why they have almost the same 49 K onset temperatures for superconductivity. The sister compound Ba2GdRuO6, either doped or not, does not superconduct, because L = 0, J 0 Gd breaks pairs and destroys superconductivity in the potentially superconducting BaO layers. High-temperature superconductivity resides in the SrO or BaO layers, or in interstitial-oxygen regions of the crystal, not in the cuprate-planes. |
