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... -
Quantum dynamics in a J_eff=1/2 isotropic triangular-lattice antiferromagnet ...
This proposal is part of our research programme to explore the spin dynamics of strongly-frustrated quantum magnets. A canonical model is the spin-1/2 triangular antiferromagnet... -
Field induced z = 2 quantum criticality in a quasi-2d quantum magnet
Quantum phase transitions have recently received a lot of interest in various different fields of physics and the emergent universal properties have been studied in very... -
Magnetic ground state of the breathing pyrochlore Ba3Yb2Zn5O11
"Breathing pyrochlores" are a new class of material that contain sublattices of corner sharing tetrahedra, where the the sizes of the tetrahedra differ on the different...
