To study the magnetic response of such an unconventional state through a bulk, thermodynamic probe, we measured the magnetic torque $\\tau$ in very high-quality, well-characterized URu$_2$Si$_2$ single-crystals \\cite{altarawneh,altarawneh2} at high magnetic-fields $H$ and at very low temperatures $T$.
