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
High magnetic field (0.5 T to 9 T) measurements of the in-plane transport critical current density Jc of YBa2Cu307 at liquid nitrogen temperature are reported as a function of the orientation of magnetic field B with respect to the a,b-plane. In contrast to earlier results at lower fields (< 3 T), t
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
