Abstract
A method for producing a high temperature superconductor (=HTS) coated conductor (12), wherein a buffer layer (2; 22) and an HTS layer (4; 24; 65) are deposited on a substrate (1; 21), with the following steps: a) after depositing the buffer layer (2; 22), the surface (2a) is locally roughened, resulting in a roughened surface (13), b) a non-superconducting, closed intermediate layer (3; 23) is deposited on top of the roughened surface (13), c) and the HTS layer (4; 24; 65) is deposited on top of the intermediate layer (3; 23). A simple method for producing a HTS coated conductor with reduced losses, and with improved critical current and critical magnetic field is thereby provided.
Claims21
A method for producing a high temperature superconductor (=HTS) coated conductor, the method comprising the steps of:
- a) selecting a substrate;
- b) depositing a buffer layer on the substrate;
- c) locally roughening, following step b), a surface of the substrate to produce a roughened surface thereof;
- d) depositing, following step c), a non-superconducting, closed intermediate layer on top of the roughened surface;
- and
- e) depositing, following step d), the HTS layer on top of the intermediate layer.
An HTS coated conductor comprising
- a substrate;
- a buffer layer or a CeO layer deposited on top of said substrate and having a roughened surface;
- a non-superconducting, closed intermediate layer or CeO intermediate layer deposited on top of said roughened surface of said buffer layer;
- and
- an HTS layer or a ReBCO type layer deposited on top of said intermediate layer.
