  • Abstract
    The critical-current and flux profile within a series of different size powders of YBa2Cu3O7 has been measured. At zero field, supercurrents flow unimpeded within the grains. However, for fields above 100 mT, it appears that the grains are subdivided on a scale smaller than 1 μm. Using this interpretation it is found that the interaction of the fluxoids with the pinning centers is very similar to that taking place in V3Si and commercial NbTi
