Magnetization studies of critical currents J~(HΒ±,T) and of the flux creep rate dlnM/dlnt have been carried out on low T~ Pb/Ge multilayers, which can be used to model the superconducting properties of the layered high Tc cuprates. By taking a proper Ge separator thickness a crossover between two dif
YBa2Cu307 crystals fabricated by a quench and melt growth process contain fine Y2BaCuO5 particles. These fine precipitates are considered to have three beneficial effects: they suppress crack formation; they promote oxygen diffusion; and they act as pinning centres. Such crystals exhibit larger flux
