Method for adjusting the threshold temperature the saturation current in the presence or absence of a magnetic field and proportions of normal conductive phases of super-conductive ceramics

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.
