An oxide superconductor article having an oxide superconductor layer of a
predetermined pattern is prepared by continuously advancing a wire having
a textured surface into a deposition zone, dispensing droplets of a
precursor solution to an oxide superconductor from a reservoir and the
depositing droplets onto the textured surface of the wire that is
introduced into the deposition zone, heating the wire or tape in the
reaction zone under conditions to convert the precursor solution into an
oxide superconductor; and collecting the wire after heating.
