TL;DR: In this article, the authors report magnetic and thermodynamic properties of single crystal ion and show that the low temperature peak in specific heat is associated with a magnetic order with unit cell doubling along the honeycomb (100) direction, consistent with zigzag order predicted within the framework of the Kitaev-Heisenberg model.

TL;DR: In this article , the authors developed and investigated a spin-wave theory for magnetic excitations applied to neutron spectroscopy, and established a convention for predicting and analyzing neutron spectra when spin-orbit coupling is a pertinent energy scale.

TL;DR: Kinoshita et al. as mentioned in this paper proposed a mechanism for the previously reported ferroelectric switching based on coupled structural and magnetic chiralities requiring only an imbalance of structural chiral domains.

TL;DR: The ground state magnetic structure, expected to be built and originate from 7 Heisenberg exchange constants, has been shown to be coupled to the underlying crystallographic chirality with polar domain switching being reported as discussed by the authors .

TL;DR: Songvilay et al. as mentioned in this paper investigated the possible origins of the momentum and energy broadened continuum scattering observed in terms of amplitude fluctuations allowed through the presence of an orbital degree of freedom on the Fe 2+ site.
