From: The nature of spin excitations in the one-third magnetization plateau phase of Ba3CoSb2O9
Calculated ordered moment within the 1/3 plateau for spin 1/2. Top row: magnitude of the reduction, \(|\delta \langle S_\mu ^x\rangle |\), of the sublattice ordered moments (normalized by S) with the designated moment directions (up or down) for (a) Jc = 0 and (b) Jc = 0.09J; for sublattices with up spins, we average \(\delta \langle S_\mu ^x\rangle\) over the corresponding two sublattices, discarding the small variance that appears for Jc > 0. Middle row: normalized staggered magnetization MUUD/S [Eq. (5)] for (c) Jc = 0 and (d) Jc = 0.09J. Bottom row: normalized (uniform) magnetization M/S for (e) Jc = 0 and (f) Jc = 0.09J. The results correspond to the local stability range of the plateau (with the precision 0.001 × 9JS for hred)
