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…

Phase Transition of the Uniaxial Disordered Ferroelectric Sr $_{0.61}$ Ba $_{0.39}$ Nb $_{2}$ O $_{6}$

S. N. Gvasaliya, R. A. Cowley, L. I. Ivleva +3

We report a neutron scattering study of a ferroelectric phase transition in Sr $_{0.61}$ Ba $_{0.39}$ Nb $_{2}$ O $_{6}$ (SBN-61). The ferroelectric polarization is along the crystallographic…

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 $_{2}$ (Cl $_{1 - x}$ Br $_{x}$ ) $_{6}$ ( $x = 0$ , x=3.5% and x=7.5…

Evolution of the neutron quasi-elastic scattering through the ferroelectric phase transition in 93%PbZn $_{1/3}$ Nb $_{2/3}$ O $_{3}$ - 7% PbTiO $_{3}$

G. -M. Rotaru, S. N. Gvasaliya, B. Roessli +3

We show that the neutron diffuse scattering in relaxor ferroelectric (1-x)PbZn $_{1/3}$ Nb $_{2/3}$ O $_{3}$ - x PbTiO $_{3}$ (x=0.07) consists of two components. The first component is…
