摘要：

Neutron-scattering and specific-heat measurements of the heavy-fermion superconductor URu2Si2 under hydrostatic pressure and with Rh-doping U(Ru0.98Rh0.02)(2)Si-2 show the existence of two magnetic phase transitions: a second-order phase transition with a tiny ordered moment and a first-order phase transition which gives rise to a large moment. The results can be understood in terms of a hidden order parameter psi linearly coupled to the dipolar ordered moment m. (C) 2004 Elsevier B.V. All rights reserved.
