Investigation of microstructure of textured YBCO with addition of nanopowder SnO2

Doping effect of Ag nanoparticles on critical current of YBa2Cu3O7−δ bulk superconductor

“…Also, they should not agglomerate and keep their nanosize character. Nanoparticles such as BaZrO 3 [8], CeO 2 [9], SnO 2 [10] and ZrO 2 [4] are successfully introduced in polycrystalline superconductors through sintering process which causes significant enhancement in critical current density. Again not many papers have investigated the effect of nanoadditive size on the critical current of superconductors.…”

Analisis Kekonduksian Lebihan Superkonduktor YBa2Cu3O7-δ Ditambah Nanozarah PbO

“…Terdapat beberapa laporan mengenai peningkatan sifat superkonduktor dengan pengedopan zarah bersaiz nano dan mikro seperti NiO, Y 2 O 3 , SnO 2 , TiO 2 dan FeF 2 (Abd-Shukor et al 2012;Campbell et al 2005;Hamid & Abd-Shukor 2000;He et al 2001;Zhao et al 2005) dalam superkonduktor suhu tinggi berasaskan kuprum oksida. Nanozarah boleh bertindak balas dengan bahan superkonduktor semasa proses penyediaan.…”

Transport critical current density of Bi–Sr–Ca–Cu–O/Ag superconductor tapes with addition of magnetic nanopowder γ-Fe2O3

“…Previous study on the conventional superconductors showed that defects in dimensions comparable to the superconducting coherence length are much more effective in pinning flux lines. Nanosize MgO increases the critical current when the maximum heat treatment temperature was 910 8C [7] but no significant enhancement in J c was observed after nanometric SnO 2 powder was added into YBCO [8].…”
