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 influence of various processing parameters on the critical currents obtained in YBCO + Ag composite thick films has been investigated. These include the use of several precursor YBCO inks produced by different calcination procedures, the effect of both processing temperature and cooling rate, an
The superconducting transition and critical current density were studied for epitaxial YBa2Cu307\_x thin films as a function of temperature, magnetic field and electric voltage gradient. A linear section of the curve of the logarithm of apparent voltage versus transport current density, In(E)-J, was
We have performed four probe transport measurements of the critical current in bulk samples of the high-Tc superconductors YBa2Cu307\_~ and DyBa2Cu3074. We found that over a range of temperatures the critical current varies linearly with (T c-T). This result indicates that these ceramics behave as a
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
