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 toward maximizing phase purity. It was found that the addition of 2% Y 2 BaCuO 5 and 0.5% Pt (by mass) ...
Growth and properties of (1x)Pb(Zn13Nb23)O3-xPbTiO3 (x=0.07-0.11) ferroelectric single crystals by a top-seeded solution growth method 热度: Effects of solidification and melt treatment on microstructure and mechanical properties of cast ZA27 alloy ...
machining/ A8110F Crystal growth from melt A7460J Critical currents in type-II superconductors A7470V Perovskite phase superconductorsA drilling procedure for obtaining superconducting rings from top seeded melt grown samples is reported. The method described is based on the use of a column drilling...
melt growth method Growth and characterization of 2-hydroxy biphenyl single crystals by top seeded melt growth methodGrowth and characterization of 2-hydroxy biphenyl single crystals by top seeded melt growth methodIn recent years, various seeding techniques were used for melt growth to obtain maximum...
The shape of single-grain bulk Y–Ba–Cu–O (YBCO) samples fabricated with and without Ca-doping by top seeded melt growth (TSMG) has been investigated. 'Standard' bulk samples of YBCO containing 0.1 wt.% Pt and enriched by 30 mol% Y 2 BaCuO 5 (Y-211) exhibit a tapered upper ...
The presence of Ag in the (RE)BCO bulk composi tion, however, typically reduces the melting temperature of the single crystal seed in the top seeded melt growth (TSMG) process, which complicates significantly the controlled nucleation and subsequent epitaxial growth of a single grain, which is...
The effects of fluorine on superconducting properties and microstructures of top-seeded melt grown YBa2Cu3O7δ bulks have been investigated through BaF2 additions (up to 1 wt% BaF2). DTA measurements show that the decomposition temperature is lowered when the content of BaF2 is increased (1003 °...
A Y2BaCuO5 buffer (Y211) block, as a diffusion barrier for samarium atoms of a top seeded melt growth (TSMG) processed YBa2Cu3O7 [?] y (Y123) superconductor using a SmBa2Cu3O7 [?] d (Sm123) seed, was examined in terms of the buffer thickness (t). Disc-type Y211 blocks wit...
