Abstract

The contribution of the Y₂Ba₁Cu₁O₅ (211) phase and the effect of Pt addition on the critical current density (J_c) of the partial-melted Y-Ba-Cu-O filaments produced by suspension spinning and solution spinning are investigated. The J_c of the filament increases by adding the Pt element, whereas the J_c of decreases with increasing the Y-rich region from the stoichiometric composition of Y₁Ba₂Cu₃O_x.
