Patent ID: 8034745

Claim:
A flexible, polycrystalline, REBCO-type, high-temperature superconducting tape with an orientation of {100}<100>or rotated {100}<100>, consisting of (a) at least one superconducting layer having non-randomly dispersed, crystalline, epitaxial columns of nanodots and/or nanorods of a non-superconducting material, aligned preferentially along the c-axis of the superconductor, with the diameter of nanodots and/or nanorods being in the range of 2-100 nanometers. (b) said REBCO superconducting layer having a composition of RE 0.8-2.0 Ba 1.5-2.5 CU 2.5-3.5 O 7-δ , where RE is selected from a group consisting of Y, Pr, Nd, Gd, Sm, Er, Eu, Pm, Dy, Ho, Tb, Tm and Lu; and their mixtures thereof, and (c) said superconducting layer further having crystalline defects aligned perpendicular to the columns of aligned nanodots or nanorods.
