Zur Kristallchemie der oxidischen Hochtemperatur‐Supraleiter und deren kristallchemischen Verwandten

Abstract: Professor Wolfgang Hilger zum 60. Geburtstag gewidmeNoch nie hat in der Geschichte der Menschheit eine chemische Substanz so viele Wissenschaftler unterschiedlichster Fachgebiete zu gemeinsamer Forschung veranlak wie der erste oxidische Hochtemperatur(HT,)-Supraleiter La, -,Sr,CuO, . Wenn die einer Stoffklasse zugeschriebene Bedeutung proportional der pro Zeiteinheit publizierten Untersuchungen ist, so halten die neuen Supraleiter mit Sicherheit den Rekord; die Flut an Literatur spiegelt zugleich auch die Erwa… Show more

“…In connection with Figure 1, we have mentioned that many superconductors are Jahn–Teller active 13–15, 19. This fact has been interpreted as a strong evidence for the el–ph nature of the pairing interaction.…”

“…The proximity between Jahn–Teller (JT) activity 12 (i.e., the stabilization of a degenerate electronic configuration by symmetry lowering) is a second widely accepted phenomenon, which has been adopted to justify the el–ph nature of the pairing interaction. Strong JT effects have been observed in many superconductors 13–15. It has been generally agreed in the physical community to identify JT distortions as evidence for a strong el–ph interaction 16.…”

“…As both have layered crystal structures, attempts for a deeper understanding and design of superconductors based on structure-property relations [3][4][5] were encouraged. The crystal structures of cuprates like YBa 2 Cu 3 O 7À d can be easily deduced from perovskites by an ordering scheme of unoccupied O sites [4]. Novel iron pnictides like FeAsSmO or BaFeAs form layered structures with sheets of [FeAs] À .…”

“…for the cuprates structural essentials and their relation to superconductivity were worked out by Hk. Müller‐Buschbaum 3,4. In particular, one‐dimensional systems feature a number of special phenomena, as there are decoupling of spin and charge excitations,5 spiral‐magnetic order inducing ferroelectricity,6 or spin‐Peierls transitions 7.…”
