Abstract :
DC transport critical current density measurements, with J/sub c/ values up to 1.4*10/sup 5/ A/cm/sup 2/ in zero field and 4.4*10/sup 4/ A/cm/sup 2/ in 1 T, performed in liquid nitrogen on melt-processed YBCO fiber from 0 to 1 T, are reported. The measurement technique is described, and the effects of contact heating and cryostabilization are discussed.<>
