Abstract

In this article, we present an experimental setup for high-pressure resistivity measurements up to 3.2 GPa and its application to EuFe2As2, a mother compound of iron-based superconductors. Hydrostatic and nonhydrostatic pressures are produced by Daphne 7474 and Stycast 1266 pressure transmitting media, respectively, using a piston-cylinder-type NiCrAl/CuBe high-pressure apparatus. It is found that, in EuFe2As2, application of hydrostatic pressure is essential for the appearance of bulk superconductivity at Tc～30 K in the limited range of 2.5-3.0 GPa. Quality of pressure generated via Daphne 7373 and 7474 are also evaluated by use of two Manganin wires arranged parallel and vertical to the load axis.
