| Abstract: | On microscopic and microstructural levels, the relations between high Tc superconductivity and percolation have been discussed. On the microscopic level, the critical oxygen concentration in YBa2Cu3O7 with Tc around 90 K has been obtained in terms of percolation. On the microstruc(?)ural level, the percolation considerations have provided, usefully theoretical basis for materials design of metal/high-Tc superconducting phase ( nonmetal) composites. |
