From the standpoint of applications, melt-processed bulk YBa[sub 2]Cu[sub 3]O[sub x] (YBCO) superconductors are of considerable interest. We have studied the microstructure and levitation force of melt-processed YBCO, YBCO plus Y[sub 2]BaCuO[sub 5], and YBCO plus Pt samples. Large single crystalline samples, grown using a seeding technique, were also studied. The levitation force is highest in melt-processed samples made by the seeding technique. 6 figs, 24 refs.
