Transport critical currents of melt-processed (QMG) YBa2Cu3Ox bulk superconductors were measured by a d.c. four probe method. The QMC bulk specimens have high Jc characterisics of = 1 x 104 A cm-2 at 5 T for the magnetic field parallel to a-b plane. The angular dependence of Jo upon the direction of

The critical current density in melt-textured samples obtained by the powder melting process was determined from magnetization measurements. Linear dependence between the width of the hysteresis loop and sample size was observed for both unirradiated and irradiated samples. This indicates that the c
The critical currents of high quality sintered YBCO tubes are measured in two configurations, namely (a) the self-field generated by the transport current is superimposed by an applied circular magnetic field generated by a current through a central wire, and (b) the self-field is superimposed by an
