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…
Magnetic anisotropy and exchange paths for octa- and tetrahedrally coordinated Mn ions in the honeycomb multiferroic MnMoO
D. Szaller, K. Szász, S. Bordács +11
We investigated the static and dynamic magnetic properties of the polar ferrimagnet MnMoO in three magnetically ordered phases via magnetization, magnetic torque, and T…
Fractional antiferromagnetic skyrmion lattice induced by anisotropic couplings
Shang Gao, H. D. Rosales, F. A. Gómez Albarracín +11
Magnetic skyrmions are topological solitons with a nanoscale winding spin texture that hold promise for spintronics applications. Until now, skyrmions have been observed in a varie…
Magneto-electric properties and low-energy excitations of multiferroic FeCr2S4
A. Strinic, S. Reschke, K. V. Vasin +5
We report on the low-frequency optical excitations in the multiferroic ground state of polycrystalline FeCr2S4 in the frequency range 0.3-3~THz and their changes upon applying exte…
Cooperative cluster-Jahn-Teller effect as a possible route to antiferroelectricity
K. Geirhos, J. Langmann, L. Prodan +8
We report the observation of an antipolar phase in cubic GaNbS driven by an unconventional microscopic mechanism, the cooperative Jahn-Teller effect of NbS molecula…
Stability of Néel-type skyrmion lattice against oblique magnetic fields in GaVS and GaVSe
B. Gross, S. Philipp, K. Geirhos +5
The orientation of Néel-type skyrmions in the lacunar spinels GaVS and GaVSe is tied to the polar axes of their underlying crystal structure through the Dzyaloshins…
Thermodynamic perspective on the field-induced behavior of -RuCl
S. Bachus, D. A. S. Kaib, Y. Tokiwa +7
Measurements of the magnetic Grüneisen parameter () and specific heat on the Kitaev material candidate -RuCl are used to access in-plane field- and temperature-dependen…
Nonequilibrium quasistationary spin disordered state in the Kitaev-Heisenberg magnet -RuCl
R. B. Versteeg, A. Chiocchetta, F. Sekiguchi +9
Excitation by light pulses enables the manipulation of phases of quantum condensed matter. Here, we photoexcite high-energy holon-doublon pairs as a way to alter the magnetic free…
Structure, phonons, and orbital degrees of freedom in FeMoO
S. Reschke, A. A. Tsirlin, N. Khan +4
We report on the structural and spectroscopic characterization of the multiferroic FeMoO. Synchrotron x-ray and neutron diffraction, as well as thermal expansion measur…
Magnetic and vibronic THz excitations in Zn doped FeMoO
B. Csizi, S. Reschke, A. Strinic +4
We report on optical excitations in the magnetically ordered phases of multiferroic FeZnMoO in the frequency range from 10-130 cm (0.3-3.9 THz). In…
Nanoscale electronic inhomogeneity in FeSeTe revealed through unsupervised machine learning
P. Wahl, U. R. Singh, V. Tsurkan +1
We report on an apparent low-energy nanoscale electronic inhomogeneity in FeSeTe due to the distribution of selenium and tellurium atoms revealed through unsupervis…
Macroscopic Manifestation of Domain-wall Magnetism and Magnetoelectric Effect in a Néel-type Skyrmion Host
K. Geirhos, B. Gross, B. G. Szigeti +12
We report a magnetic state in GaVSe which emerges exclusively in samples with mesoscale polar domains and not in polar mono-domain crystals. Its onset is accompanied with a…
