Magnetic fields applied to anisotropic Kitaev chains produce ordered phases with four-site, large-unit-cell, and six-site uniform-chirality periodicities, explained by an effective model containing transverse Ising, Dzyaloshinskii-Moriya, and further-neighbor Ising interactions.
NLCE calculations on the J-K-Γ model for α-RuCl3 show that the linear magnetostriction coefficient perpendicular to the plane exhibits a dip-like feature tied to the suppression of magnetic order.
