High-pressure ac specific heat technique with cubic anvil apparatus

Abstract

We report the development of ac specific heat technique under highly hydrostatic pressures using a cubic anvil apparatus. The constructed system is sensitive enough to detect a magnetic phase transition, pressure up to 8 GPa and temperature range between 2 and 30 K. We present the results of specific heat measurement of ternary iron arsenide EuFe2As2 single crystal up to 4.0 GPa with the technique presented here. © 2010 IOP Publishing Ltd.
