The effect of Sm addition on the microstructure and superconducting properties of Y–Ba–Cu–O (YBCO) bulk superconductors has been studied. Nominal composition: 1 mol YBa2Cu3O7_+ 0.25 mol Y2O3+ 1 wt% CeO2 was enriched with different amounts of SmBa2Cu3Oy powder with the aim to increase critical current density, Jc, especially in higher magnetic fields by introducing additional pinning centers. Single grain YBCO bulk superconductors with SmBa2Cu3Oy (Y123-Sm) addition were prepared by the optimized top seeded melt growth process.
