Book 1990oups have also claimed the presence of superconductivity in tetragonal phases. Whether oxygen ordering plays or not a crucial role for the superconductivity remains to be seen. However it is clear that the ordering of oxygens and their thermodynamic properties is an interesting subject on its own ri

Oxygen Stoichiometry and Superconductivity in Ceramicsm high frequency susceptibility measurements follows this behavior; a fast decrease in T. up to a plateau around 60 K. The volume fraction of superconducting material decreases steadily, until the sample becomes non-superconducting.

Book 19908-21, 1989 at the International Centre for Theoretical Physics, Trieste, Italy. It was recognized very early in the field of ceramic superconductors that oxygen plays a crucial role as far as the physical properties of these ma terials are concerned. The preparation requires special heating and coo
