The addition of silver to YBa2Cu3O7− δ (Y123) is well known to decrease its decomposition
temperature. This study demonstrates the success in welding large Y123 textured samples …

Segregation and competition of Y-based impurities in Y-rich biepitaxial YBCO samples is
investigated. The analysis of distribution and microstructure of the precipitates is performed …

The influence of the ratio of small and large size YBa2Cu3Ox (Y123) starting powders on the
microstructure development in the sintered and melt-textured YBa2Cu3O7/Y2BaCuO5 …

The influence of a cerium/tin doping mixture on top seeded melt textured pellets of YBa 2 Cu
3 O 7− δ/Y 2 BaCuO 5 (Y123/Y211) was investigated and compared with cerium doping …

YBCO pellets have been submitted to the top-seeding melt-textured growth process under a
reduced oxygen atmosphere (1% O 2 in Ar). Ce and (Ce, Sn) doping have been …

Bars of REBa2Cu3Oy superconductor with three different rare earths were prepared by
floating zone technique in air. Their nominal composition is (RE0. 33Eu0. 33Gd0. 33) …

In this paper, we reported the effect of Cu doping on the structural and dielectric properties of
Ba _ 2 Y _ 1-x Cu _ x TaO _ 6-y Ba 2 Y 1-x Cu x TaO 6-y (0.00 ≤ x ≤≤ x≤ 0.50) ceramics …

Pellets of cerium plus tin doped YBa2Cu3O7–δ (Y123) were textured using the top seeding
melt texturing growth method. Amounts of SnO2 varying from 0.25 to 1.00 wt.% were added …

We have grown cubic centimeter-size crystals of YBa 2 Cu 3 O x suitable for neutron studies,
by a top-seeded melt-growth technique. Growth conditions were optimized with an eye …

Abstract Single-domain, c-axis-oriented 30 mm diameter Zn-doped Dy–Ba–Cu–O/Ag
(DyBCO) bulk superconductors have been successfully grown by the top-seeded melt …
