Abstract

The problem of separating YBCO crystals from solidified residual melts could be solved by systematic growth experiments. Free crystals up to 7×7 mm2 area and about 0.1 mm thickness could by obtained from a BaO-CuO solvent and small alumina crucibles. Superconductivity was revealed by levitation and Meissner effect.
