We fabricated c-axis oriented large grain (Sm,Eu,Gd)Ba 2 Cu 3 O 7Àd bulk superconductors with BaO 2 addition under 1% O 2 partial pressure in Ar. The experiment showed that BaO 2 addition significantly reduced a RE-Ba substitution, slightly hindered the coarsening of (Sm,Eu,Gd) 2 BaCuO 5 inclusion,
