The ground state of the simple Heisenberg nearest-neighbor quantum kagome antiferromagnetic model is a magnetically disordered spin liquid, yet various perturbations may lead to fundamentally different states. Here we disclose the origin of magnetic... Read More about Origin of Magnetic Ordering in a Structurally Perfect Quantum Kagome Antiferromagnet.

Magnetism and Néel skyrmion dynamics in GaV4S8−ySey (2020)
Journal Article
Hicken, T., Holt, S., Franke, K., Hawkhead, Z., Štefančič, A., Wilson, M., Gomilšek, M., Huddart, B., Clark, S., Lees, M., Pratt, F., Blundell, S., Balakrishnan, G., & Lancaster, T. (2020). Magnetism and Néel skyrmion dynamics in GaV4S8−ySey. Physical Review Research, 2(3), Article 032001. https://doi.org/10.1103/physrevresearch.2.032001

We present an investigation of the influence of low levels of chemical substitution on the magnetic ground state and Néel skyrmion lattice (SkL) state in GaV4S8−ySey, where y=0,0.1,7.9, and 8. Muon-spin spectroscopy (μSR) measurements on y=0 and 0.1... Read More about Magnetism and Néel skyrmion dynamics in GaV4S8−ySey.
