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…
