Texturing of DyBa₂Cu₃O₇ superconducting grains synthesized in situ in a magnetic field

Synthesis of DyBa₂Cu₃O₇ superconducting ceramics has been made in a small magnetic field (H=0.6 T) for different sample geometries and thermal cycles. The sample is placed in a vertical furnace and in a horizontal magnetic field. Control experiments (H=0) have been performed in each case for the same conditions. We have found texturing and terrace substructures. Thus the magnetic field is relevant for texturing and growth.
