From: The nature of spin excitations in the one-third magnetization plateau phase of Ba3CoSb2O9

Neutron diffraction data for Ba3CoSb2O9 at 0 and 10 T. (a) q = (1/3, 1/3, 0) and (b) q = (1/3, 1/3, 1) measured at T = 1.5 K. c Comparison of the diffraction intensities between the experiment and the simulation at T = 1.5 K and μ0H = 10 T (the solid line is a guide to the eye). Error bars represent one standard deviation
