TRANSPORT-PROPERTIES OF MAGNETICALLY TEXTURED YBA2CU3O7-DELTA

A new process has been developed in which bulk textured YBa2Cu3O7-delta ceramics have been prepared by solidification in a magnetic field. The electrical transport properties of this field textured material are discussed. The temperature dependence of the electrical resistivity in fields of up to 4.5 T are presented. Transport critical current densities at 77 K in magnetic fields of up to 7 T are reported. For currents flowing along the a-b planes and a magnetic field of 6.9 T applied parallel to both the a-b planes and to the direction of current flow, transport critical current densities of 15 200 A/cm2 were observed. Variations in the critical current density with the magnitude and direction of the applied field are also discussed.
