Hidden Magnetic Octupolar Order driven by Spin-Orbit coupling in KFeF $_{3}$

C. A. Crawford, C. I. Hiley, N. C. Bristowe +6

Phase transitions are typically driven by symmetry-breaking structural distortions that lift electronic degeneracies, yet in some cases, these transitions may be driven by a hidden…

Anisotropic excitonic magnetism from discrete $C_{4}$ symmetry in CeRhIn $_{5}$

D. J. Brener, I. Rodriguez Mallo, H. Lane +6

Anisotropy in strongly correlated materials is a central parameter in determining the electronic ground state and is tuned through the local crystalline electric field. This is not…

Spin-orbital correlations from complex orbital order in MgV $_{2}$ O $_{4}$

H. Lane, P. M. Sarte, K. Guratinder +12

MgV $_{2}$ O $_{4}$ is a spinel based on magnetic V $^{3 +}$ ions which host both spin ( $S = 1$ ) and orbital ( $l_{e f f} = 1$ ) moments. Owing to the underlying pyrochlore coordination of the…

Neutron diffraction in MnSb2O6: Magnetic and structural domains in a helicoidal polar magnet with coupled chiralities

E. Chan, J. Pásztorová, R. D. Johnson +10

MnSb $_{2}$ O $_{6}$ is based on the structural chiral $P$ 321 space group #150 where the magnetic Mn $^{2 +}$ moments ( $S = 5/2$ , $L \approx 0$ ) order antiferromagnetically at $T_\mathrm{N…

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…
