Critical End Points in Heavy Fermion URu2Si2"

Abstract:
I shall review the tiny moment magnetism and the basic hidden
order properties of this superconducting heavy fermion material
and then consider the pressure dependences of the tiny moments
via neutron scattering and NMR. Large magnetic fields can destroy
the hidden order and lead to itinerant electron metamagnetism and
the possibility of a quantum critical end point at 38 T.
