Abstract :
[en] We report a complete procedure to achieve multilayer YBCO thick films by
electrophoretic deposition on silver tubes using a suspension of YBCO powder in butanol. With
the aim to optimize the magnetic shielding performances of the coatings, we have carried out an
extensive investigation of the influence of the deposition parameters, the multilayer deposition
sequence and the intermediate/final heat treatments on the coating microstructure. Using the
optimized conditions, a 24-layer YBCO coating has been successfully prepared on an 80 mm
long Ag tube: the melt growth processed multilayered YBCO thick film thus obtained can shield
an applied magnetic field of 1.9 mT at 77 K, the highest value per thickness unit reported so far
in the literature for these materials.
