Abstract

The recently discovered superconductivity in the titled materials, at 45 K and 90 K, respectively, is almost as surprising phenomenologically as high-temperature superconductivity (HTSC) itself. Nevertheless, the microscopic theory of filamentary intermediate phases, recently developed for semiconductor impurity bands and layered HTSC cuprates, and even for network glasses, explains the existence of these phenomena with no new assumptions. The ultimate mechanism responsible for filamentary formation is self-organization, which minimizes the dopant-related free energy at the formation temperature.
