Abstract
YBCO nanopowder consisting of 1-3 nm thick and 40 nm wide particles has been used to make silver clad superconducting tapes. After annealing in nitrogen at 945 degreesC for 10 h a critical current of 5.02 A (3300 A/cm(2)) was attained, Annealing in mixed atmosphere of oxygen and nitrogen was also carried out and this procedure produced tapes with a critical current of 2.83 A (2200 A/cm(2)). These tapes show very good characteristics in magnetic fields. (C) 2002 Elsevier Science B.V. All rights reserved.
