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…
Quantum Paraelectricity in the Kitaev Quantum-Spin-Liquid Candidates HLiIrO and DLiIrO
K. Geirhos, P. Lunkenheimer, M. Blankenhorn +7
H3LiIr2O6 is the first honeycomb-lattice system without any signs of long-range magnetic order down to the lowest temperatures, raising the hope for the realization of an ideal Kit…
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…
