In this paper the critical density for a polycrystalline sample is calculated assuming a model of weakly coupled superconducting grains and the influence of grain size on the maximum tunnelling current is investigated. In addition the Josephson vortices are shown to be bound by the pinning force inh
Using a temperature measurement, the field induced dissipation in polycrystalline YBa2Cu30 x at T,~ T c has been measured for magnetic fields up to 2970 Oe applied at constant ramp rates, in the absence of a transport current. At 4.85 K results show that for H > 500 Oe the dissipated energy was rate
