a Schematic of spin clusters used to calculate the structural factors. The 120° configurations with approximately zero net spin give rise to the pattern in which high intensity is near the zone boundary. The FM clusters lead to the pattern where high intensity is near the zone center. b–d Comparison of the structural factors by the cluster and flavor wave calculations. Both methods reproduce the scattering in Ni2Mo3O8 at 12–16 meV (b), 18–22 meV (d), and the sum of two (c).
