Abstract
Studies of 50- mu m-thick films of YBa/sub 2/Cu/sup 3/O/sub 7- delta / on yttria-stabilized zirconia rods, which have been melt-processed using an infrared furnace, are reported. The results indicate that J/sub c/'s higher than the 3000 A/cm/sup 2/ achieved so far are not impossible. Transport and magnetization results suggest that the increase in J/sub c/ is due to alignment of the grains along the axis of the rod. This is confirmed by the scanning electron microscopy photographs, which show an increase in grain size and alignment.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
