Thermally Enhanced Pseudo-Goldstone Spin Gap in the Isotropic Helimagnet ZnCrSe
N. D. Andriushin, A. Sanders, J. Reuther +8
In magnetically ordered systems, the spin gap in the magnon spectrum is normally expected to decrease on warming and close at the transition out of the long-range order. The presen…
Electron-phonon coupling in EuAl4 under hydrostatic pressure
A. S. Sukhanov, S. Gebel, A. N. Korshunov +7
In the intermetallid rare-earth tetragonal EuAl4 system, competing itinerant exchange mechanisms lead to a complex magnetic phase diagram, featuring a centrosymmetric skyrmion latt…
Competition Between Multiferroic and Magnetic Soliton Lattice States in DyFeO
S. E. Nikitin, N. D. Andriushin, Ø. S. Fjellvåg +5
Simultaneous breaking of time reversal and inversion symmetries in multiferroics couples ferroelectricity to magnetism and is a source of unusual physical phenomena that can be use…
Spiral Spin Liquid State in the Corrugated Honeycomb Lattice of CaMnP
Farhan Islam, Nikita D. Andriushin, Thaís V. Trevisan +9
CaMnP exemplifies the realization of a frustrated -- Heisenberg model of a corrugated honeycomb magnetic lattice. Previous studies show that below the Néel t…
Observation of the spiral spin liquid in a triangular-lattice material
N. D. Andriushin, S. E. Nikitin, Ø. S. Fjellvåg +7
The spiral spin liquid (SSL) is a highly degenerate state characterized by a continuous contour or surface in reciprocal space spanned by a spiral propagation vector. Although the…
Anomalous quasielastic scattering contribution in the centrosymmetric multi- helimagnet SrFeO
N. D. Andriushin, J. Grumbach, A. A. Kulbakov +14
Centrosymmetric compounds which host three-dimensional topological spin structures comprise a distinct subclass of materials in which multiple- magnetic order is stabil…
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…
Phonon softening and atomic modulations in EuAl
A. N. Korshunov, A. S. Sukhanov, S. Gebel +6
EuAl is a rare earth intermetallic in which competing itinerant and/or indirect exchange mechanisms give rise to a complex magnetic phase diagram, including a centrosymmetric s…
Phonon topology and winding of spectral weight in graphite
N. D. Andriushin, A. S. Sukhanov, A. N. Korshunov +3
The topology of electronic and phonon band structures of graphene is well studied and known to exhibit a Dirac cone at the K point of the Brillouin zone. Here, we applied inelastic…
Rich Magnetic Phase Diagram of Putative Helimagnet SrFeO
Nikita D. Andriushin, Justus Grumbach, Jung-Hwa Kim +14
The cubic perovskite SrFeO was recently reported to host hedgehog- and skyrmion-lattice phases in a highly symmetric crystal structure which does not support the Dzyaloshinskii…
Slow spin dynamics and quantum tunneling of magnetization in the dipolar antiferromagnet DyScO
N. D. Andriushin, S. E. Nikitin, G. Ehlers +1
We present a comprehensive study of static and dynamic magnetic properties in the Ising-like dipolar antiferromagnet (AFM) DyScO\ by means of DC and AC magnetization measuremen…
