Search for magnetic long-range order in a spin-liquid candidate K2Ni2(SO4)3
We recently synthesised a new compound, K2Ni2(SO4)3, that allows the existence of non-trivial topologicalphases such as skyrmions. Specific heat measurements show the existence... -
Magnetic Phase Separation in a Frustrated Antiferromagnet
Frustrated magnetic materials are interesting because they show unusual behaviour arising from a near-degeneracy of ground states. The magnetic order of MgCr2O4 - apparently... -
