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
The critical current density in melt-textured samples obtained by the powder melting process was determined from magnetization measurements. Linear dependence between the width of the hysteresis loop and sample size was observed for both unirradiated and irradiated samples. This indicates that the c
