Abstract
Y2BaCuO5 (211) bars sintered at high temperatures were used as substrates in melt processing of long YBa2Cu3O7−x (123) bars. Use of high-density 211 substrates (sintered at 1250°C for 12 h) resulted in less liquid extraction, as compared to low-density 211 bars (sintered at 940°C for 24 h). In addition, it was found that the high-density bars influence the texture of 123, as domains were observed to grow from the 211123 interface. A 6 cm long single domain sample with a cross-sectional area of 0.54 cm2 was melt processed by using a 211 substrate. A dc transport critical current of 1500 A along the c-direction of this full-length bar was measured at 77 K and in a self-field.
