We report Shubnikov-de Haas oscillation measurements within the high magnetic field (μ0H>39 T) magnetically polarized regime of URu2Si2, made possible using mesoscopic samples prepared by means of focused ion beam lithography. A significant change in the Fermi surface topology relative to the "hidden-order" phase is observed, signaling a transformation into a high magnetic field regime in which 5f-electrons are removed from the Fermi surface. URu2Si2 is therefore a rare example of an actinide compound in which a transformation of 5f-electrons can be directly observed at low temperatures, setting the stage for the unconventional ordering and high magnetic field quantum criticality in this material. © 2013 American Physical Society.
