Abstract
The pressure and magnetic-field effects on a Hg0.82Re0.18Ba2Ca2Cu3O8+delta Sample with optimum oxygen content was studied. The onset temperature of th e dissipation (T-on) for a fixed applied magnetic held increases with the p ressure. The H(T-on) curves, taken at different pressures, may be superpose d when T-on is scaled with the pressure-dependent critical temperature, T-c (P), suggesting that the mechanism which leads to an increase of T-c also i mproves the intergrain coupling. Our data are discussed in the frame of the phase slippage model giving some insight on the influence of the pressure on the transport properties of our sample.
