| Research Abstract |
Development for high pressure measurement apparatus for Hall effect on Pr cuprate superconductor Pr2Ba4Cu7O15-δ has been performed. Modification of Bridgman type high pressure apparatus with Teflon capsule made it possible to measure electrical resistivity measurement above 10 GPa. Resistivity measurement on Pr2Ba4Cu7O15-δ shows maximum at 11 GPa, which corresponds to the structural transition around 10 GPa.
