Observation of superconductivity (T-c=50 K) in a new tetragonal alkaline-earth cuprate Sr0.8Ba1.2CuO3+delta, synthesised at ambient pressure

The ambient-pressure synthesis of a new tetragonal alkaline-earth superconducting cuprate, Sr0.8Ba1.2CuO3+δ, from a cupro-oxycarbonate is reported. Magnetic-susceptibility measurements show the presence of a superconducting transition ∼ 50 K in a post-annealed sample. The crystal structure, refined...
