Topological magnon insulators in two-dimensional van der Waals ferromagnets CrSiTe and CrGeTe: towards intrinsic gap-tunability
Fengfeng Zhu, Lichuan Zhang, Xiao Wang +14
The bosonic analogues of topological insulators have been proposed in numerous theoretical works, but their experimental realization is still very rare, especially for spin systems…
Lattice dynamics coupled to charge and spin degrees of freedom in the molecular dimer-Mott insulator -(BEDT-TTF)Cu[N(CN)]Cl
Masato Matsuura, Takahiko Sasaki, Satoshi Iguchi +11
Inelastic neutron scattering measurements on the molecular dimer-Mott insulator -(BEDT-TTF)Cu[N(CN)]Cl reveal a phonon anomaly in a wide temperature range. Starting…
Investigation of the spin-1 honeycomb antiferromagnet BaNiVO with easy plane anisotropy
E. S. Klyushina, B. Lake, A. T. M. N. Islam +6
The magnetic properties of the two-dimensional, S=1 honeycomb antiferromagnet BaNiVO have been comprehensively studied using DC susceptibility measurements and inelasti…
Higgs mode and its decay in a two dimensional antiferromagnet
A. Jain, M. Krautloher, J. Porras +9
Condensed-matter analogs of the Higgs boson in particle physics allow insights into its behavior in different symmetries and dimensionalities. Evidence for the Higgs mode has been…
Spin-wave excitations evidencing the Kitaev interaction in single crystalline -RuCl
Kejing Ran, Jinghui Wang, Wei Wang +13
Kitaev interactions underlying a quantum spin liquid have been long sought, but experimental data from which their strengths can be determined directly is still lacking. Here, by c…
Soft spin-amplitude fluctuations in a Mott-insulating ruthenate
A. Jain, M. Krautloher, J. Porras +9
Magnetism in transition-metal compounds (TMCs) has traditionally been associated with spin degrees of freedom, because the orbital magnetic moments are typically largely quenched.…
Magnon spectrum of the helimagnetic insulator Cu2OSeO3
P. Y. Portnichenko, J. Romhanyi, Y. A. Onykiienko +11
Complex low-temperature ordered states in chiral magnets are typically governed by a competition between multiple magnetic interactions. The chiral-lattice multiferroic Cu2OSeO3 be…
Competing exchange interactions on the verge of a metal-insulator transition in the two-dimensional spiral magnet SrFeO
J. -H. Kim, Anil Jain, M. Reehuis +12
We report a neutron scattering study of the magnetic order and dynamics of the bilayer perovskite SrFeO, which exhibits a temperature-driven metal-insulator transition…
