## 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
Intergrowth structures, which occur in the HgBa2Ca2Cu3Oy ceramic superconductor, were observed by means of transmission electron microscopy (TEM). There are at least two types of intergrowth structure: Hg-1212/Hg-1223 and Hg-1223/Hg-1234. The congruence relationships for these intergrowth structures
The onset temperature ( T,) of the Meissner signal for HgBaZCa2Cu30, (which is 134 K under normal pressure) has been measured under high pressure up to 11 GPa. It is observed that T, increases with increasing pressure at the rate of dT,/dP= 2.0 K/ GPa and then dT./dPbecomes relatively small above 6
