Description
We investigate the phase transition of URu2Si2 at T0 = 17.5 K by thermal expansion and heat capacity in magnetic fields, H, up to 25 T. At T0 an energy gap of Δ ≅ 115 K opens, which decreases to 65 K in 25 T. The H dependence of T0 scales with Δ, whereas a different H dependence and energy scale was observed for the ordered dipole moment. The anomalous H dependence of the thermal expansion coefficients may discriminate between the various scenarios for the primary order parameter of URu2Si2. (orig.)
