Abstract

Ag sheathed (Bi<inf>1.6</inf>Pb<inf>0.4</inf>)Sr<inf>2</inf>Ca<inf>2</inf>Cu<inf>3</inf>O<inf>y</inf>(Co<inf>3</inf>O<inf>4</inf>)<inf>x</inf> superconductor tapes with addition of Co<inf>3</inf>O<inf>4</inf> nanoparticles (with size 30 and 50) were fabricated using the powder-in-tube (PIT) method. The structure and microstructure were studied along with critical temperature (T<inf>c</inf>) and transport critical current density (J<inf>c</inf>). The nanoparticle added tapes showed a higher J<inf>c</inf> value compared with the non-added tapes. The 30-nm Co<inf>3</inf>O<inf>4</inf> added tapes showed a higher J<inf>c</inf> value compared with the 50 nm Co<inf>3</inf>O<inf>4</inf> added tapes. This study showed that Co<inf>3</inf>O<inf>4</inf> nanoparticles could act as effective pinning centers leading to enhancement of J<inf>c</inf> in the Bi-2223/Ag sheathed tapes. The addition of smaller Co<inf>3</inf>O<inf>4</inf> nanoparticles (30 nm) results in stronger pinning. The full vortex magnetic energy due to addition of Co<inf>3</inf>O<inf>4</inf> magnetic nanoparticles led to the enhancement of J<inf>c</inf>.
