THE CONCENTRATION AND TEMPERATURE TRANSITION TO SUPERCONDUCTING STATE IN FULLERIDES OF ALKALI METALS

摘要

The statistical theory of phase transition in fullerides of alkali metals to superconducting state has been elaborated. The calculation of free energy of crystals has been performed on the basis of molecular-kinetic notion and the equilibrium equations have been examined. The critical temperature of superconductivity has been estimated, its concentration dependence has been ascertained. The calculation results have been compared with experimental data. The numerical estimation for energetic parameters of pairing of Cooper pairs electrons has been performed.
