## From magnetization studies for the grain aligned HgBa2CazCu30, superconductor the temperature variation of critical current density J,(T) values was characterized by an exponential decay of the form J, a exp (-T/T,). Flux pinning was significantly greater with the peak F P, ,,,(T) shifted to h

The scaling behavior of the effective activation energy of high-quality epitaxial c-oriented Bi 2 Sr 2 Ca(Cu 1Γx Co x ) 2 O d thin films with 0 6 x P 0.025 has been studied as a function of temperature and magnetic field. For all samples, the effective activation energy scales as U(T, l 0 H) = U 0 (
Surplus and deficient regions of Hg, Pb and TI atoms are found at some edges of a typical Hgo.55Pbo.asTlo.2BazCa2Cu3Oy superconducting grain. The formation of these regions can be explained by a simple model which takes into account the growth of grains during the Hg superconducting phase formation
The Hall effect of high-temperature superconducting (HTCS) Ho-Ba-Cu-O thin films has been measured in applied magnetic fields up to 90 kOe in the region close to the superconducting onset temperature. The 90 kOe Hall coefficient R. decreases to zero from the superconducting onset temperature in a wa
A dense and grain-oriented Bi0.85Pb0.,5Sr0.8CaCu,.40v superconductor was prepared by hot-pressing. The lower critical field (H,, ) and Josephson lower critical field (H,,,) due to the weak link between grains were measured from initial magnetization curves. Anisotropy in H,,, was observed below 77
