Abstract

In an attempt to increase remanant supercurrent density in a (Nd_0.33E_0.33Gd_0.33)Ba₂- Cu₃O_y superconductor by a long-term ball milling of the inserted secondary phase, it was possible to reach outstanding J_c values of 192 and 110 kA/cm² at remanent state and 3 T. Microstructure analysis by DFM and TEM revealed the presence of a new type of particle, 20-50 nm in size.
