Time reversal symmetry and magnetoelastic correlations are probed by means ofhigh-resolution volume dilatometry in URu2Si2 at cryogenic temperatures andmagnetic fields more than enough to suppress the hidden order state at H_HO(T =0.66 K) approximately 35 T. We report a significant crystal lattice volumeexpansion at and above H_HO(T), and even above T_HO, possibly a consequence offield-induced f-electron localization, and hysteresis at some high field phaseboundaries that confirm volume involvement. We investigate in detail themagnetostriction and magnetization as the temperature is reduced over twodecades from 50 K where the system is paramagnetic, to 0.5 K in the realms ofthe hidden order state. We find a dominant quadratic-in-field dependence deltaL/L proportional to H^2, a result consistent with a state that is symmetricunder time reversal. The data shows, however, an incipient yet unmistakableasymptotic approach to linear (delta L/L proportional to 1-H/H_0) for 15 T < H< H_HO(0.66 K) approximately 35 T at the lowest temperatures. We discuss theseresults in the framework of a Ginzburg-Landau formalism that proposes a complexorder parameter for the HO to model the (H,T,p) phase diagram.
