Abstract
A high-temperature superconductor having low superconducting anisotropy includes a two-dimensional layered structure of crystal unit cells each consisting of a pair of superconducting layer and charge reservoir layer. At least a portion of the atoms of the charge reservoir layer are replaced by atoms giving superconductivity, rendering the charge reservoir layer superconducting and lowering the superconducting anisotropy by increasing the coherence length in the thickness direction.
