【 摘 要 】

We carried out powder neutron diffraction measurements in NaCuMoO4(OD) in order to investigate the ground state of this material. We observe no temperature dependence between the powder neutron diffraction profiles at T = 1.2 and 0.07 K within the experimental error. We evaluate the maximum of the expected moment under the assumption that the helical magnetic order is realized and that the magnetic peaks are hidden in background scattering. We determined the positions of the D ions from the profile by using the Rietveld analysis.
