Abstract

Microstructure and critical current density of the melt-textured (Sm_0.33Eu_0.33Gd_0.33)Ba₂Cu₃O_y (SEG-123) superconductors with varying contents of Gd₂BaCuO₅ (Gd-211) were studied by means of scanning electron microscopy, transmission electron microscopy (TEM), and magnetic measurements with SQUID. The TEM study showed sub-micron secondary phase particles regularly distributed in the SEG-123 matrix. The homogeneous distribution of Gd-211 resulted in a dramatically improved remanent critical current density, even in the samples with only 10 mol% Gd-211. The second peak height did not appreciably change with varying content of Gd-211 up to 30 mol%. Critical current density as high as 83 kA/cm² was achieved at 77 K and magnetic field of 2.2 T along c-axis.
