Abstract

(Bi1.6Pb0.4)Sr2Ca2Cu 3O10-(NiO) x superconductor with x=0, 0.01, 0.02, 0.03, 0.04, and 0.05 wt.% was prepared using the coprecipitation technique. The average size of NiO used was 8 nm and 16 nm. The highest value of the transport critical current density, J c in the bulk form was observed in the x=0.01 wt.% samples for both sizes. Based on this result, Ag sheathed superconductor tapes with starting composition (Bi1.6Pb 0.4)Sr2Ca2Cu3O10-(NiO) 0.01 (with NiO particle size 8 and 16 nm) were fabricated using the powder-in-tube method. The effect of these nanoparticles addition on the microstructure, phase formation, and transport critical current density were studied. The J c of the tape at 77 K in zero fields with NiO (8 nm) addition (4500 A/cm2) was slightly higher than that of NiO (16 nm) added tape (4120 A/cm2). The nonadded tape showed a lower J c (1080 A/cm2 at 77 K). These results indicated that magnetic nanoparticles such as NiO could act as an effective flux pinning centers leading to the enhancement of J c in the bulk and tape form. Moreover, NiO with size closer to the coherence length, ξ was more effective in enhancing J c.
