Description
The high-temperature phase Hg Ba Ca Cu O (HBCCO) compound with an onset transition temperature Tc ∼ 135 K has been investigated under hydrostatic pressure up to 12 kbar. We found a positive pressure effect on Tc with a rate 0.2 K/kbar and a positive pressure effect on the transport critical current Jc dln(Jc)/dp=0.2 ± 0.02 K/kbar. The observation of the strong hysteresis effect in Jc vs magnetic field H dependencies show the possibility of surface barriers to vortex motion in the high-Tc HBCCO system
