Spin dynamics in natural multiferroic pyroxene NaFeSiO
Oleksandr Prokhnenko, Stanislav E. Nikitin, Koji Kaneko +8
Spin dynamics in the natural mineral aegirine, NaFeSiO, a member of the pyroxene family, was studied by elastic and inelastic neutron scattering. Magnetization and specific…
Bullet pressure-cell design for neutron scattering experiments with horizontal magnetic fields and dilution temperatures
Ellen Fogh, Gaétan Giriat, Richard Gaal +10
The simultaneous application of high magnetic fields and high pressures for controlling magnetic ground states is important for testing our understanding of many-body quantum theor…
Helical Spin Dynamics in Commensurate Magnets: a Study on Brochantite, CuSO(OH)
S. E. Nikitin, Tao Xie, A. Gazizulina +8
We report the direct observation of a commensurate-ordered antiferromagnetic (AFM) state but incommensurate helical spin dynamics in the natural mineral brochantite CuSO(OH…
Magnetic ground state of the frustrated spin-1/2 chain compound -TeVO at high magnetic fields
M. Pregelj, A. Zorko, M. Klanjšek +7
Frustrated spin-1/2 chains, despite the apparent simplicity, exhibit remarkably rich phase diagram comprising vector-chiral (VC), spin-density-wave (SDW) and multipolar/spin-nemati…
Dispersions of Many-Body Bethe strings
Anup Kumar Bera, Jianda Wu, Wang Yang +9
Complex bound states of magnetic excitations, known as Bethe string, were predicted almost a century ago to exist in one-dimensional quantum magnets 1. The dispersions of the strin…
