The; (Bi; Pb) 2 Sr2 Ca2 Cu3 O10 - (Fe3 O4) x superconductor for x=0; 0.01; 0.03; and 0.05 were prepared. The average size of Fe3 O4 used was 40 nm. The maximum critical current density (Jc) in the bulk form was observed in the x=0.01 sample. Based on this result; Ag sheathed high temperature superconductor tapes with starting compositions (Bi; Pb) 2 Sr2 Ca2 Cu3 O10 - (Fe3 O4) 0.01 were fabricated using the powder in tube method. The microstructure; phase formation; critical temperature; and transport critical current density were studied. The Jc of the nanosized Fe3 O4 added tapes is 5130 A/ cm2 at 77 K and 23130 A/ cm2 at 30 K in zero fields. The nonadded tapes showed a lower Jc; 3090 A/ cm2 at 77 K and 12 400 A/ cm2 at 30 K. A sudden decrease in Jc in low magnetic fields (B;
