Abstract

     This paper deals with a new description of the structure of high Tc superconductors. We show that these structures can be described as a result of  an Order-Disorder mechanism  from a high symmetry latent cubic phase.

 

Keywords: Superconductor; Structure; Oorder-disorder; Hhigh symmetry.
