Dynamics and thermodynamics of the S = 5/2 almost Heisenberg triangular lattice antiferromagnet K2Mn(SeO3)2
Mengze Zhu, V. Romerio, D. Moser +7
We report calorimetric, magnetic, and neutron scattering studies on an S = 5/2, nearly Heisenberg triangular-lattice antiferromagnet K2Mn(SeO3)2 with weak XXZ easy-axis anisotropy.…
Dielectric relaxation by quantum critical magnons
Daniel Flavián, Pavel A. Volkov, Shohei Hayashida +4
We report the experimental observation of dielectric relaxation by quantum critical magnons. Complex capacitance measurements reveal a dissipative feature with a temperature-depend…
Spin pseudogap in Ni-doped SrCuO2
G. Simutis, S. Gvasaliya, M. Mansson +11
The S=1/2 spin chain material SrCuO2 doped with 1% S=1 Ni-impurities is studied by inelastic neutron scattering. At low temperatures, the spectrum shows a pseudogap Δ~ 8 meV, absen…
Field-induced criticality in a gapped quantum magnet with bond disorder
D. Hüvonen, S. Zhao, M. Månsson +6
Neutron diffraction and calorimetric measurements are used to study the field-induced quantum phase transition in piperazinium-Cu(ClBr) (, x=3.5% and x=7.5…
