Query: Re-entrant hidden order at a metamagnetic quantum critical end point   Magnetization measurements of URu2Si2 in pulsed magnetic fields of 44 T
reveal that the hidden order phase is destroyed before appearing in the form of
a re-entrant phase between ~ 36 and 39 T. Evidence for conventional itinerant
electron metamagnetism at higher temperatures suggests that the re-entrant
phase is created in the vicinity of a quantum critical end point.
