[en] We report measurements and analysis of the specific heat and magnetocaloric effect-induced temperature changes at the phase boundary into the single magnetic field-induced phase (phase II) of U(Ru(0.96)Rh(0.04))(2)Si(2), which yield irreversible properties similar to those at the valence transition of Yb(1-x)Y(x)InCu(4). To explain these similarities, we propose a bootstrap mechanism by which lattice parameter changes caused by an electric quadrupolar order parameter within phase II become coupled to the 5f-electron hybridization, giving rise to a valence change at the transition.
