A SIMPLE EMPIRICAL EQUATION FOR ESTIMATING CRITICAL TEMPERATURES OF COPPER OXIDE SUPERCONDUCTORS

摘要

We found a simple empirical equation for estimating critical temperatures of the cooper-based superconductors. This relationship can predict which structural configuration may lead to very high temperature superconductivity. Our equation takes into account the particularity of the rock-salt blocks that sandwiches the CuO_2 layers (the mass and the coordinates of the ions). The evaluated critical temperatures are in good agreement with the experimental data.
