Transport properties of high critical temperature superconductors
An overview of the transport properties of new high temperature oxide superconducting materials is presented. In particular, the transport critical current in single crystals and sintered material is examined. The intrinsic properties of the new superconductors can be explained in terms of a low pinning energy and of the usual mechanisms of thermally activated flux motion. In sintered samples, the superconducting behaviour is dominated by the poor intergrain coupling that leads to the formation of Josephson weak links between grains.
