# A kagome map of spin liquids from XXZ to Dzyaloshinskii–Moriya ferromagnet

@article{Essafi2016AKM, title={A kagome map of spin liquids from XXZ to Dzyaloshinskii–Moriya ferromagnet}, author={Karim Essafi and Owen Benton and Ludovic D. C. Jaubert}, journal={Nature Communications}, year={2016}, volume={7} }

Despite its deceptive simplicity, few concepts have more fundamental implications than chirality, from the therapeutic activity of drugs to the fundamental forces of nature. In magnetic materials, chirality gives rise to unconventional phenomena such as the anomalous Hall effect and multiferroicity, taking an enhanced flavour in the so-called spin-liquid phases where magnetic disorder prevails. Kagome systems sit at the crossroad of these ideas. Motivated by the recent synthesis of rare-earth… Expand

Kagome antiferromagnet: a chiral topological spin liquid?

- Physics, Medicine
- Physical review letters
- 2012

At low temperatures, it is found that quantum fluctuations favor this chiral phase, which is stable against small perturbations of second- and third-neighbor interactions, and thermal fluctuations compete with quantum ones and induce a transition from this flux phase to a planar zero flux phase at a nonzero value of the renormalized temperature.
