COATED CONDUCTORS WITH REDUCED A.C. LOSS

摘要

Coated conductors (40) and methods of fabricating the same are provided, for minimizing a.c. losses during operation. Multilayered articles include multiple conductive layers (46, 47) in electronic communication through interlayer connections (54, 60). Conductive paths (50) are fabricated on the conductive layers and through interlayer connections between these layers so that current travels the length of the conductors with minimal a.c. losses. Preferably at least one of the superconductive layers (46, 47) is formed epitaxially on a substrate (42) covered with a biaxially textured buffer layer (44), the interlayer connections (54, 60) traversing an insulating or highly resistive layer (49).
