Abstract
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.
