AbstractAmong strongly correlated states of matter, spin liquids stand as one of the best understood theoretically but the least understood experimentally. In RuCl$_3$, inelastic neutron scattering and Raman spectroscopy reveal a continuum of excitations that persist to high temperature, in accordance with Kitaev’s prediction for a spin liquid state on a honeycomb lattice. However, the effects of high magnetic fields - comparable to the spin exchange energy scale - have not been explored. Here we report measurements of the magnetotropic coefficient - the second derivative of the free energy with respect to magnetic field orientation - over a wide range of magnetic fields and temperatures. Unlike conventional spin systems, which polarize and become isotropic at high fields, the magnetization in RuCl$_3$ shows no signs of saturation up to 65 Tesla. Furthermore, temperature and magnetic field compete to determine the magnetic response in a way that is independent of the large exchange energy. This scale-invariant magnetic response is a new signature of the spin-liquid state that goes beyond current predictions of the Kitaev model.
