Architecture for High Critical Current Superconducting Tapes

Abstract
A composite structure for achieving high critical current densities in
superconductive tapes where the composite structure is a multilayer
structure or architecture including a structure of a first layer of a
superconducting rare-earth-barium-copper oxide from about 0.2 microns to
about 2 microns in thickness, a layer of an insulating material from the
group of cerium oxide, strontium titanate, yttrium oxide, magnesium oxide,
and yttria-stabilized zirconia, or of a conducting material of strontium
ruthenium oxide, and a second layer of a superconducting
rare-earth-barium-copper oxide from about 0.2 microns to about 2 microns in
thickness, the superconducting structure characterized as having a total
combined thickness of superconducting rare-earth-barium-copper oxide layers
of at least 2 microns.
