摘要：

X-ray diffraction, electron microprobe analyses, resistivity and magnetisation of YBaCuO coatings obtained by plasma spraying in air are presented. The sample heated at 1000 C in air and annealed at 450 C in oxygen has a Tc = 92.5 K. The transport critical current density at 77 K measured by the pulsed current technique is around 70 A/cm2. The intragranular critical current derived from the magnetisation studies at 10 K is of the order of 105 A/cm2at low fields. © 1990.
