Abstract
ABSTRACTWe present the results of our systematic investigation of the RE dependency of superconductivity in the parent compounds T’-RE2CuO4 (RE = Pr, Nd, Sm, Eu, Gd, and Tb). Superconducting samples were prepared by metal organic decomposition (MOD). A stringent control of synthesis- and post-annealing-conditions is required to obtain superconducting samples. Superconductivity with a transition temperature (Tconset) ≥ 30 K is achieved for RE = Pr and Nd. By contrast, Tconset is at highest 20 K for RE = Gd. Our results indicate that the induction of superconductivity into T’-RE2CuO4 cuprates strongly depends on the RE3+ ionic size. This trend is discussed from the viewpoint of RE-dependent thermodynamic stability of T’-RE2CuO4. For smaller RE3+ ions, the thermodynamic boundary conditions become tighter.
