Abstract
The critical currents (I c) of hot-pressed Bi0.85Pb0.15Sr0.8CaCu1.4O y ceramics with different cross-sectional areas were measured at 77 K in zero magnetic field. I c was approximately proportional to the cross-sectional area. It seems that transport current flows uniformly across the cross-section of the sample.Keywords
