Phonons reflect dynamic spin-state order in LaCoO
Alsu Ivashko, Taishun Manjo, Maximilian Kauth +17
We investigate lattice dynamics in LaCoO using inelastic neutron and x-ray scattering over $T = 2\mbox{-}650\,\mathrm{K}$, spanning the spin-state crossover at $T_{1} \approx 1…
Charge-density-wave quantum critical point under pressure in 2-TaSe
Yuliia Tymoshenko, Amir-Abbas Haghighirad, Rolf Heid +13
Suppressing of an ordered state that competes with superconductivity is one route to enhance superconducting transition temperatures. Whereas the effect of suppressing magnetic sta…
Reentrant multiple- magnetic order and a "spin-cholesteric" phase in SrFeO
N. D. Andriushin, J. Muller, N. S. Pavlovskii +11
Spin-nematic and spin-smectic phases have been reported in magnetic materials, which break rotational symmetry while preserving translational symmetry along certain directions. How…
Adherence of the rotating vortex lattice in the noncentrosymmetric superconductor RuB to the London model
A. S. Cameron, Y. V. Tymoshenko, P. Y. Portnichenko +6
The noncentrosymmetric superconductor RuB has in previous studies demonstrated remarkably unusual behaviour in its vortex lattice, where the nearest neighbour directions of…
Singlet-triplet mixing in the order parameter of the noncentrosymmetric superconductor RuB
A. S. Cameron, Y. S. Yerin, Y. V. Tymoshenko +8
One of the key effects which is predicted to arise in superconductors without a centre of inversion is the mixing of singlet and triplet order parameters, which are no longer good…
Frustration model and spin excitations in the helimagnet FeP
A. S. Sukhanov, Y. V. Tymoshenko, A. A. Kulbakov +14
The metallic compound FeP belongs to the class of materials that feature a complex noncollinear spin order driven by magnetic frustration. While its double-helix magnetic structure…
Magnetic-field dependence of low-energy magnons, anisotropic heat conduction, and spontaneous relaxation of magnetic domains in the cubic helimagnet ZnCr2Se4
D. S. Inosov, Y. O. Onykiienko, Y. V. Tymoshenko +12
Anisotropic low-temperature properties of the cubic spinel helimagnet ZnCr2Se4 in the single-domain spin-spiral state are investigated by a combination of neutron scattering, therm…
Lattice dynamics in the double-helix antiferromagnet FeP
A. S. Sukhanov, S. E. Nikitin, M. S. Pavlovskii +10
We present a comprehensive investigation of lattice dynamics in the double-helix antiferromagnet FeP by means of high-resolution time-of-flight neutron spectroscopy and ab-initio c…
Magnonic Weyl states in Cu2OSeO3
L. Zhang, Y. A. Onykiienko, P. M. Buhl +8
The multiferroic ferrimagnet CuOSeO with a chiral crystal structure attracted a lot of recent attention due to the emergence of magnetic skyrmion order in this material. He…
Rotation of the magnetic vortex lattice in Ru7B3 driven by the effects of broken time-reversal and inversion symmetry
A. S. Cameron, Y. S. Yerin, Y. V. Tymoshenko +7
We observe a hysteretic reorientation of the magnetic vortex lattice in the noncentrosymmetric superconductor Ru7B3, with the change in orientation driven by altering magnetic fiel…
Pseudo-Goldstone magnons in the frustrated S=3/2 Heisenberg helimagnet ZnCr2Se4 with a pyrochlore magnetic sublattice
Y. V. Tymoshenko, Y. A. Onykiienko, T. Mueller +13
Low-energy spin excitations in any long-range ordered magnetic system in the absence of magnetocrystalline anisotropy are gapless Goldstone modes emanating from the ordering wave v…
Magnetic phase diagram of the helimagnetic spinel compound ZnCr2Se4 revisited by small-angle neutron scattering
A. S. Cameron, Y. V. Tymoshenko, P. Y. Portnichenko +7
We performed small-angle neutron scattering (SANS) measurements on the helimagnetic spinel compound ZnCr2Se4. The ground state of this material is a multi-domain spin-spiral phase,…
