We studied in detail the low temperature/high magnetic field phases of URu2Si2 single crystals with specific heat, magnetocaloric effect, and magnetoresistance in magnetic fields up to 45 T. Data obtained down to 0.5 K, and extrapolated to T=0, show a suppression of the hidden-order phase at H0(0)=35.9\ifmmode±\else\textpm\fi0.35 T and the appearance of a new phase for magnetic fields in excess of H1(0)=36.1\ifmmode±\else\textpm\fi0.35 T observed only at temperatures lower than 6 K. In turn, complete suppression of this high field state is attained at a critical magnetic field H2(0)=39.7\ifmmode±\else\textpm\fi0.35 T. No phase transitions are observed above 40 T. We discuss our results in the context of itinerant versus localized f electrons.
