Abstract

A comprehensive neutron diffraction stud of the magnetic structure at T = 1.5 K was performed. Overall, 35 inequivalent magnetic Bragg intensities were measured. Although the obtained value for the ordered moment m0 = 0.12μB is much smaller than in KCuF3, it was large enough to expect a measurable spin-wave contribution to inelastic scattering.
