<p>A tape-type superconductor (1), comprising
- an elongated substrate (2), in particular a metal tape, and
- a continuous superconducting layer (3), in particular of a HTS type material, deposited on the substrate (2), is characterized in that
l c ll / l c Š¥ ‰¥ 1.5, with l c ll being the density of critical current of the continuous superconducting layer (3) in parallel to the substrate (2) and in parallel to the elongated direction of the substrate (2), and with l c Š¥ being the density of critical current of the continuous superconducting layer (3) in parallel to the substrate (2) and perpendicular to the elongated direction of the substrate (2). The invention provides a tape-type superconductor with reduced ac losses.</p> |
