We investigated the crystal and magnetic structures of the spin-1/2 frustrated antiferromagnet Cu3Mo2O9 in which the spin system consists of antiferromagnetic chains and dimers. The space group at room temperature has been reported to be orthorhombic P nma (No. 62). We infer that the space group above TN = 7.9 K is monoclinic P 21/m (No. 11) from the observation of reflections forbidden in P nma in x-ray powder diffraction experiments at room temperature. We determined the magnetic structure of Cu3Mo2O9 in neutron powder diffraction experiments. Magnetic moments on dimer sites lie in the ac planes. The magnitudes are 0.50 ∼ 0.74µB. Moments on chain sites may exist but the magnitudes are very small. The magnetic structure indicates that a partial disordered state is realized. We consider the origin of the magnetic structure, weak ferromagnetism, and electric polarization.

Successive phase transitions to antiferromagnetic and weak-ferromagnetic long-range order in the quasi-one-dimensional antiferromagnetCu3Mo2O9

et al. 2008

Investigation of the magnetism of Cu 3 Mo 2 O 9 single crystal, which has antiferromagnetic ͑AF͒ linear chains interacting with AF dimers, reveals an AF second-order phase transition at T N = 7.9 K. Although weakferromagnetic-like behavior appears at lower temperatures in low magnetic fields, complete remanent magnetization cannot be detected down to 0.5 K. However, a jump is observed in the magnetization below weakferromagnetic ͑WF͒ phase transition at T c Ӎ 2.5 K when a tiny magnetic field along the a axis is reversed, suggesting that the coercive force is very weak. A component of magnetic moment parallel to the chain forms AF long-range order ͑LRO͒ below T N , while a perpendicular component is disordered above T c at zero magnetic field and forms WF-LRO below T c . Moreover, the WF-LRO is also realized by applying magnetic fields even between T c and T N . These results are explainable by both magnetic frustration among symmetric exchange interactions and competition between symmetric and asymmetric Dzyaloshinskii-Moriya exchange interactions.

“…Hence, for a better understanding of electrochemical properties and mechanism involved for charging‐discharging of Cu 3 [MoO 4 ] 2 O as an anode material, not only morphology but also crystal structure analysis is crucial. The Cu 3 [MoO 4 ] 2 O structure was analyzed based on an investigation of Steiner et al . Figure shows the structure analysis of Cu 3 [MoO 4 ] 2 O microspheres as Steiner et al.…”

Flower‐like Cu3[MoO4]2O microspheres have been synthesized by using a sequential process from lindgrenite (Cu3(MoO4)2(OH)2). Lindgrenite nanoflowers were synthesized through a simpler route by using an aqueous chemical precipitation technique at room temperature without any surfactants or template. Subsequently, 3D flower‐like Cu3[MoO4]2O microspheres have been synthesized by annealing at 300 °C for 2 h from lindgrenite (Cu3(MoO4)2(OH)2). From the XRD pattern, FTIR spectrum, SEM and TEM analysis, flower‐like Cu3[MoO4]2O (ca. 5 μm) microspheres have been obtained, which were assembled from 3–4 nm thick nanosheets with an orthorhombic structure. Application of 3D flower‐like microspheres as an anode material for lithium‐ion batteries (LIBs) has been investigated and the possible electrochemical mechanism is analyzed. Electrochemical characterization of the Cu3[MoO4]2O nanoflowers as an anode material for LIBs has exhibited good cycle stability and a high coulombic efficiency during operation. The electrochemical activity was attributed to the unique structure of the Cu3[MoO4]2O microspheres, which provide more active sites for Li‐ion storage as well as a reduced transfer resistance. This work has explored a simple synthesis strategy for the synthesis of flower‐like Cu3[MoO4]2O microspheres without templates, additives, or surfactants, which exhibit a basis for not only high electrochemical performance in reversible Li storage, but also cycle stability.
