Control of Y-211 content in bulk YBCO superconductors fabricated by a buffer-aided, top seeded infiltration and growth melt process
Bulk (RE)–Ba–Cu–O ((RE)BCO, where RE stands for rare-earth), single grain superconductors can trap magnetic fields of several tesla at low temperatures and therefore can function potentially as high field magnets. Although top seeded melt growth (TSMG) is an established process for fabricating relatively high quality single grains of (RE)BCO for high field applications, this technique suffers f...
متن کاملFlux pinning in Al doped TSMG YBCO bulk superconductors
The superconducting properties of Y1Ba2(Cu1−x Alx)3O7/Y2BaCuO5 bulk superconductors with different Al contents were studied (x = 0.0025–0.05). A peak effect was observed at intermediate magnetic fields over a wide temperature range below Tc. The influence of standard oxygenation (SO) at 400 ◦C and high pressure oxygenation (HPO) at 750 ◦C on the critical current density Jc was investigated. We ...
متن کاملexploring motivation and english test preparation strategies of iranian pre-university candidates during and at the end of test preparation period for konkur examination
the current study aimed at investigating the relationship between motivation and test preparation strategies (tpss) used by iranian pre-university students in their preparation period for the university entrance exam (uee). due to the importance of uee in iran, this study also attempted to show its impact on these two important variables. to this end, 100 pre-university students in an iranian p...
Dissolution and Resolidification of SmBa2Cu3O7-y Seed during Top Seeded Melt Texturing of YBa2Cu3O7-y
During top-seeded melt growth of YBa2Cu3O7-y (Y123) single-domained crystal, seed dissolution occurred while the seed is in contact with Ba-Cu-O liquid, and then the dissolved parts were resolidified during cooling. The growth mode of Y123 crystal was directly affected by the resolidification process of the dissolved part. When the melted part of the seed was resolidified to polycrystal, Y123 ...
متن کاملThe influence of post-growth thermal treatments on the critical current density of TSMG YBCO bulk superconductors
Oxygenation and thermochemical post-growth treatments of top seeded melt-growth (TSMG) YBCO bulk superconductors can significantly influence critical current density. It is shown that, depending on oxygenation conditions and the size of 211 particles, different reductions of intrinsic critical current density values can be obtained due to the reduction in the sample cross-section caused by the ...
