Investigating field-induced magnetic order in Han Purple by neutron scattering up to 25.9 T
S. Allenspach, A. Madsen, A. Biffin +14
BaCuSiO is a quasi-two-dimensional (2D) quantum antiferromagnet containing three different types of stacked, square-lattice bilayer hosting spin-1/2 dimers. Although this c…
Multiple Magnetic Bilayers and Unconventional Criticality without Frustration in BaCuSiO
S. Allenspach, A. Biffin, U. Stuhr +9
The dimerized quantum magnet BaCuSiO was proposed as an example of "dimensional reduction" arising near the magnetic-field-induced quantum critical point (QCP) due to perfe…
Observation of two types of anyons in the Kitaev honeycomb magnet
N. Janša, A. Zorko, M. Gomilšek +6
Quantum spin liquid is a disordered magnetic state with fractional spin excitations. Its clearest example is found in an exactly solved Kitaev honeycomb model where a spin flip fra…
Magnetic field dependence of excitations near spin-orbital quantum criticality
A. Biffin, Ch. Rüegg, J. Embs +4
The spinel FeScS has been proposed to realize a near-critical spin-orbital singlet (SOS) state, where entangled spin and orbital moments fluctuate in a global singlet state…
Non-coplanar and counter-rotating incommensurate magnetic order stabilized by Kitaev interactions in -Li2IrO3
A. Biffin, R. D. Johnson, I. Kimchi +5
Materials that realize Kitaev spin models with bond-dependent anisotropic interactions have long been searched for, as the resulting frustration effects are predicted to stabilize…
A new spin-anisotropic harmonic honeycomb iridate
Kimberly A. Modic, Tess E. Smidt, Itamar Kimchi +14
The physics of Mott insulators underlies diverse phenomena ranging from high temperature superconductivity to exotic magnetism. Although both the electron spin and the structure of…
