METHOD FOR ADJUSTING CRITICAL TEMPERATURE OF CERAMIC SUPERCONDUCTOR, SATURATION CURRENT DENSITY IN MAGNETIC AND NON-MAGNETIC FIELDS AND NORMAL CONDUCTION PHASE RATIO

摘要

Method for adjusting the critical temperature, the saturation current density in the presence or absence of a magnetic field and the proportions of normally conducting phases of ceramic superconductors having a structure derived from perovskite by altering the content of the electronegative component, or if a plurality are present, of one of the electronegative components in the ion lattice of the superconductor directly on the substrate.
