文摘It has been reported by J. G. Bendnorz and K. A. M(?)ller that there is possible high Tc superconductivity in the Ba-La-Cu-O system. This system exhibits a number of oxygen-deficient phases with mixed-valent copper constituents, and this gives rise to itinerant electronic states between the non-Jahn-Teller Cu+++ and Jahn-Teller Cu++ ions. Strong electron-phonon interaction might lead to superconducting phase transition.
