Flux 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 کاملControl 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 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 ...
متن کاملLiquid-solid joining of bulk metallic glasses
Here, we successfully welded two bulk metallic glass (BMG) materials, Zr51Ti5Ni10Cu25Al9 and Zr50.7Cu28Ni9Al12.3 (at. %), using a liquid-solid joining process. An atomic-scale metallurgical bonding between two BMGs can be achieved. The interface has a transition layer of ~50 μm thick. The liquid-solid joining of BMGs can shed more insights on overcoming their size limitation resulting from thei...
متن کاملAssessing the spatial and field dependence of the critical current density in YBCO bulk superconductors by scanning Hall probes
Although the flux density map of a bulk superconductor provides in principle sufficient information for calculating the magnitude and the direction of the supercurrent flow, the inversion of the Biot–Savart law is ill conditioned for thick samples, thus rendering this method unsuitable for state of the art bulk superconductors. If a thin (<1 mm) slab is cut from the bulk, the inversion is reaso...
