Microwave properties of DyBCO monodomain in the mixed state and comparison with other RE-BCO systems
N. Pompeo, R. Rogai, M. Ausloos +4
We report on microwave measurements on DyBaCuO monodomains grown by the top-seeded melt-textured technique. We measured the field increase of the surface resista…
Microwave properties of DyBa_2Cu_3O_(7-x) monodomains and related compounds in magnetic fields
N. Pompeo, E. Silva, M. Ausloos +1
We present a microwave characterization of a DyBaCuO single domain, grown by the top-seeded melt-textured technique. We report the (a,b) plane field-induced sur…
Magnetic shielding properties of high-temperature superconducting tubes subjected to axial fields
Samuel Denis, Laurent Dusoulier, Michel Dirickx +4
We have experimentally studied the magnetic shielding properties of a cylindrical shell of BiPbSrCaCuO subjected to low frequency AC axial magnetic fields. The magnetic response ha…
Synthesis and characterization of Bi2Sr2CaCu2O8 ceramics prepared in presence of sodium
S. Rahier, S. Stassen, R. Cloots +1
This paper aims to study Na doping in Bi-2212 superconducting ceramics. Na-doped Bi-2212 samples powders with a Bi2-uSr2-vCa1-wCu2-xNayOz stoichiometry are prepared by means of the…
Influence of Na-doping and sintering temperature on increasing Bi2Sr2CaCu2O8 superconducting phase content in powder form materials
S. Rahier, S. Stassen, R. Cloots +1
This paper proposes a systematic way to explore the effects of Na on Bi-2212 phase formation. The influence of sodium metal is correlated with the 2212 fraction formed in the sampl…
