    Notes: Abstract Superconducting carbides of the rare earth metals and the novel layered carbide halides of these metals, both containing C2 units, present model systems to study the origin of pairwise attraction between conduction electrons in terms of a tendency towards pairwise localization. The superconducting transition temperature scales with the effective charge of the C2 unit as well as with the size of the metal atom cage around C2. From a materials aspect superconductivity and giant magnetoresistance are related as indicated by the new GMR material GdI2 which structurally and in view of chemical bonding parallels the superconducting niobium and tantalum dichalcogenides.

    Notes: The microscopic theory of superconductivity worked out by Bardeen, Cooper, and Schrieffer led to a fundamental understanding of the phenomenon. However, this theory does not provide a materials aspect. Starting from the special situation of chemical bonding in carbides and carbide halides of the rare earth metals a general view of the origin of superconductivity is developed, based on a tendency for (pairwise) localization of conduction electrons. This approach is tested in terms of special features in the electronic band structure and compared with existing physical models of electron pairing in real space. Its applicability to high-temperature superconductors discovered during the last decade is discussed.
