Critical current density of ceramic high-temperature superconductors in a low magnetic field

The transport critical current densities, ←J c→, of bulk sintered YBaCuO and Bi(Pb)SrCaCuO samples in the shape of slabs have been measured at 77 K as a function of the slab thickness, d, and of a weak applied magnetic field, H a, ( H a⩽20 Oe, H a ← J c→). It was found that the transport critical cu...
