Oxidation Annealing Effects on the Spin-Glass-Like Magnetism and Appearance of Superconductivity in T*-type La1−x/2Eu1−x/2SrxCuO4 (0.14 ≤ x ≤ 0.28)

We investigated the magnetism and superconductivity in as-sintered (AS) and oxidation annealed (OA) T*-type La1−x/2Eu1−x/2SrxCuO4 (LESCO) with 0.14 ≤ x ≤ 0.28 by the first comprehensive muon spin r...
