Metastable antiphase boundary ordering in CaFe $_{2}$ O $_{4}$

H. Lane, E. E. Rodriguez, H. C. Walker +11

CaFe $_{2}$ O $_{4}$ is an $S = 5/2$ antiferromagnet exhibiting two magnetic orders which shows regions of coexistence at some temperatures. Using a Green's function formalism, we model…

Two-dimensional ferromagnetic spin-orbital excitations in the honeycomb VI $_{3}$

H. Lane, E. Pachoud, J. A. Rodriguez-Rivera +6

VI $_{3}$ is a ferromagnet with planar honeycomb sheets of bonded V $^{3 +}$ ions held together by van der Waals forces. We apply neutron spectroscopy to measure the two dimensional (…

From one- to two-magnon excitations in the S=3/2 magnet $β$ -CaCr $_{2}$ O $_{4}$

M. Songvilay, S. Petit, F. Damay +7

We apply neutron spectroscopy to measure the magnetic dynamics in the S=3/2 magnet $β$ -CaCr $_{2}$ O $_{4}$ (T $_{N}$ =21 K). The low-energy fluctuations, in the ordered state, resemble large…

Kitaev interactions in the Co honeycomb antiferromagnets Na $_{3}$ Co $_{2}$ SbO $_{6}$ and Na $_{2}$ Co $_{2}$ TeO $_{6}$

M. Songvilay, J. Robert, S. Petit +10

Co $^{2 +}$ ions in an octahedral crystal field, stabilise a j $_{e f f}$ = 1/2 ground state with an orbital degree of freedom and have been recently put forward for realising Kitaev in…

Decay and renormalization of a longitudinal mode in a quasi-two-dimensional antiferromagnet

Seung-Hwan Do, Hao Zhang, Travis J. Williams +8

An ongoing challenge in the study of quantum materials, is to reveal and explain collective quantum effects in spin systems where interactions between different modes types are imp…

Neutron scattering investigation of proposed Kosterlitz-Thouless transitions in the triangular-lattice Ising antiferromagnet TmMgGaO4

Zhiling Dun, Marcus Daum, Raju Baral +10

The transverse-field Ising model on the triangular lattice is expected to host an intermediate finite-temperature Kosterlitz-Thouless (KT) phase through a mapping of the spins on e…
