(RE,Y)-123 SUPERCONDUCTING FILM CONTAINING MIXED ARTIFICIAL PINNING CENTERS AND PREPARATION METHOD THEREOF
The invention relates to a (RE,Y)-123 superconducting film containing mixed artificial pinning centers and a preparation method thereof, wherein a stoichiometric ratio of Cu in a parent phase of the (RE,Y)-123 superconducting film is 3.05-5; the mixed artificial pinning centers include a perovskite structure BaMO3 and a double-perovskite structure oxide Ba2(RE,Y)NO6; and a total mole percentage of Ba2(RE,Y)NO6 in the superconducting film is not less than 2.5%. The mixed artificial pinning centers form well-aligned column structures along the thickness direction in the superconducting film. The invention is intended not only to solve the problem that a single secondary phase cannot be well aligned along the thickness direction of (RE,Y)-123 when using the high-speed pulsed laser deposition technique, but also to effectively overcome the film thickness effect of the (RE,Y)-123 superconducting film containing mixed artificial pinning centers, hence the in-field current carrying capacity of the superconducting film is significantly improved in industrialized high-speed production.
