Jl. Gonzalez et al., Influence of the pressure on the onset of the dissipation in Hg0.82Re0.18Ba2Ca2Cu3O8+delta ceramic superconductor, PHYSICA C, 341, 2000, pp. 485-486
The pressure (P) effect on a Hg0.82Re0.18Ba2Ca2Cu3O8+delta Sample with opti
mum oxygen content is presented. The onset temperature of the dissipation (
T-co) increases with P. The T-co(H) curves, taken at different pressures, a
re superposed when T-co were scaled with T-c(P), suggesting that the mechan
ism which leads to an increasing of T-c also improves the intergrain coupli
ng. Our data is discussed in the frame of the phase slippage model giving s
ome insight on the microscopic effects of the pressure.
