Abstract

Large grain bulk superconductors with various compositions: SmBa2Cu3O7-δ, (Sm0.5Eu0.5)Ba2Cu3 O7-δ, and EuBa2Cu3O7-δ have been successfully fabricated in air. The scaling studies of the volume pinning force evidenced two competitive pinning contributions at low and high fields for all compositions. The analyses of the scaling curves showed that the low field pinning kept identical for three compositions, while in high fields, the dominant pinning for Sm123 and Eu123 was the small-sized normal core pinning and the δTc pinning in SE123.
