The I–V characteristics of magnetron glow discharges with a Y 1 Ba 2 Cu 3 O 7−δ superconductor cathode are studied and found to have anomalously low operating voltage, negative resistance and strong hysteresis effects. The energy dependence of t

We describe a simple post-deposition annealing technique for crystallizing very smooth (10 nm rms surface roughness) thin films of YBa2Cu3O7−δ (123) on SrTiO3 at low temperatures. The method does not rely on matching oxygen partial pressures and m

The complete reaction pathway describing the degradation of YBa2Cu3O7−δ by ZrO2 is determined. Initial dissociation of the superconductor into Y2BaCuO5, CuO and BaCuO2 is in accordance with the YBaCuO ternary phase diagram. Subsequent decompositio

We describe a method of high temperature annealing in which the control of oxygen partial pressure is the principal experimental determinant in obtaining highly c ⊥ oriented thin films of YBa 2 Cu 3 O 7 − δ on YSZ. Film crystallization, morpholo

The intra- and intergranular components of resistance in high- T c superconductors are modelled, after configurational averaging, as due to a single resistively shunted Josephson junction in each case. They are combined in series. A voltage develops

Thin films of YBa2Cu3O7_ deposited by ion-beam sputtering on yttria-stabilised zirconia (YSZ)substrates at room temperature have been lithographically patterned to form dc SQUID structures. Weaklinks are formed by naturally-occurring grain boundaries

The transport properties of thin film high Tc superconductors in large magnetic fields depend on microstructure; in particular grain size, the degree of grain orientation with c-axis normal to the film plane, the degree of a (b)-axis alignment of adj
