The effect of (Nd<sub>0.33</sub>Eu<sub>0.33</sub>Gd<sub>0.33</sub>)<sub>2</sub>BaCuO<sub>5</sub> (NEG-211), and Gd<sub>2</sub>BaCuO<sub>5</sub> (Gd-211) additions on melt-processed (Nd<sub>0.33</sub>Eu<sub>0.33</sub>Gd<sub>0.33</sub>)Ba<sub>2</sub>Cu<sub>3</sub>O<sub>y</sub> (NEG-123) composites are investigated using a combination of transmission electron microscopy (TEM) and measurements of critical current densities, J <sub>c</sub>. TEM observations demonstrate that we could successfully embed submicron-size 211 particles within the NEG-123 matrix. EDX analysis revealed that these submicron-size particles consist Maynly of Gd in the rare earth site. The presence of such 211 particles leads to a dramatic increase of J <sub>c</sub> in low fields as well as in the high field region. For NEG-123 with an addition of 40 mol% of NEG-211 a critical current density of 70 000 A/cm<sup>2</sup> at 77 K, 2.2 T is observed for the field applied parallel to the c axis. |
