摘要：

We have performed elastic and inelastic neutron-scattering measurements on the heavy-fermion superconductor URu2Si2 in a magnetic field of 12 T along the c-axis of the tetragonal crystal structure. The small ordered moment and the energy gap in the magnetic excitation spectrum shaw a comparable transition temperature in a magnetic field of 12 T. This is in disagreement with recent predictions of a decoupling of the ordered moment and the energy gap in high magnetic fields.
