A simple device to measure high pressure resistivity at temperatures upto 500K

摘要

A simple device to measure high pressure resistivity at temperature upto 500K is designed. It is a modification of Bridgman opposed anvil device. By external heating the performance of the device is tested with reported results upto 4 GPa and upto temperature 500K for bismuth. Here principle, design and the efficiency of the device are explained. Using this device, high pressure resistivity behaviour upto 4 GPa and upto 500 K of oxide Yba{sub}1.6La{sub}0.4Cu{sub}3O{sub}(7±δ) is investigated and the results are discussed.
