Abstract

We fabricated c-axis oriented large grain (Sm,Eu,Gd)Ba₂Cu ₃O_7-δ bulk superconductors with BaO₂ addition under 1% O₂ partial pressure in Ar. The experiment showed that BaO₂ addition significantly reduced a RE-Ba substitution, slightly hindered the coarsening of (Sm,Eu,Gd)₂BaCuO₅ inclusion, and improved the superconducting properties. An optimum adding amount was around 0.06-0.18 per mol RE123. At 77 K, the critical current density reached 83,000 A/cm² at zero field.
