Abstract

A new parameter named PESATc (Parametro Estructural de los Superconductores de Alta Temperatura critica) is presented and used to discuss an aproach to the 'Stripe Phases' in (La,Ca)MnO3 superconductors. The PESATc parameter is based on the superposition of an Octahedrical Moebius Strip over the CuO planes and apical oxygen O(4). The linear correlation between PESATc and Tc for Rare Earth based perovskite compound is shown.
