Abstract

Combination of neutron scattering and thermal expansion measurements under pressure shows that the so-called hidden order phase of URu2Si 2 reenters in magnetic field when antiferromagnetism (AF) collapses at HAF(T). Macroscopic pressure studies of the HO-AF boundaries were realized at different pressures via thermal expansion measurements under magnetic field using a strain gauge. Microscopic proof at a given pressure is the reappearance of the resonance at Q0 = (1,0,0) under field which is correlated with the collapse of the AF Bragg reflections at Qo.
