Аннотация:
Bi-based polycrystalline HTSC coatings deposited over silver cylindrical substrates have been studied by phase X-ray analysis. Obtained coatings have been found to be textured due to distinctions of rates of the crystal growth in different crystallographic directions, enhanced by surface curvature. The degree of texture of the coatings is dependent both on the substrate curvature and on thermal treatment. For the orthorhombic 2201 phase, the grade of texture is higher than that for the tetragonal 2201 phase.
