Abstract

Elastic neutron-scattering and ac-susceptibility measurements have been performed on a 2 φ single crystal of URu2 Si2 under hydrostatic pressure up to ∼ 1.1 GPa using Fluorinert 70 & 77 and Daphne oil 7373 as pressure-transmitting media. Daphne oil produces better hydrostaticity of the applied pressure than Fluorinert, resulting in a slight shift of the phase boundary between hidden order and antiferromagnetic order to a lower pressure. The superconducting phase is also influenced, but never overlaps with the antiferromagnetic phase.
