| Abstract | ||
| High temperature superconductors with a nominal composition HgBa2Ca2Cu3O8+δ for different values of pressure (0.2,0.3, 0.5, 0.6, 0.9, 1.0 & 1.1)GPa were prepared by a solid state reaction method. It has been found that the samples were semiconductor P=0.2GPa.while the behavior of the other samples are superconductor in the rang (80-300) K. Also the transition temperature Tc=143K is the maximum at P is equal to 0.5GPa. X-ray diffraction showed a tetragonal structure with the decreasing of the lattice constant c with the increasing of the pressure. Also we found an increasing of the density with the pressure. | ||
