Abstract

Oxide superconductors such as Ba Pb1-x Bix O3 and the tetragon La2-x Mx Cu O4 - (M=Ba,Sr) systems have a very narrow range of compositions in which high superconducting transition tempera- tures occur. Their high Tc's are caused by a strong electron - phonon interaction which is present in only a narrow range of compositions and crystal structure.
