Abstract
The successful extrusion of short lengths of brittle wires of YBa2Cu3O y that are superconducting above 77 K is reported. Detailed critical current measurements are presented on wires having undergone different physical treatments. The highest critical current obtained from V-I data is ⋍ 90 A/cm2, but this particular wire shows clear evidence of flux-pinning forces corresponding to ⋍ 130 A/cm2.
