26 Jan 2019 | Abstract: | Among 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. | Source: | arXiv, 1901.9245 | Services: | Forum | Review | PDF | Favorites |
