- $YBa_{2}Cu_{3}O_{7-δ }$ (YBCO, Y-123) bulk superconductors with a nominal composition $Y_{1.5}Ba_{2}Cu_{3}O_{x}$ and 1 wt% $CeO_{2}$ addition were prepared by the Top Seeded Melt Growth (TSMG) process. Small single-crystalline pieces, cut from the $SmBa_{2}Cu_{3}O_{y}$ (Sm-123) bulk, were used for seeding of epitaxial growth. Wavelength-dispersive spectrometry (WDS) confirmed the presence of 0.1 wt% Sm from the seed and 0.25 wt% Yb from the substrate, practically in the whole sample volume. The influence of this Sm and Yb contamination on superconducting properties of grown bulk materials is reported.
