 Abstract: A transition metal oxide, NbMoO4, is synthesized by using a solid-state reaction method, then the morphology of the sample is characterized by the scanning electron microscopy. The X-ray diffraction refinement and transmission electron microscopy results show that the sample has a TiO2 rutile-type structure with space group P4(2)/mnm, which is the high-temperature phase of NbO(2 )and MoO2. Our transport result indicates that the resistivity is as low as 0.02 Omega.cm in the temperature range from 2 to 300 K, indicating the metallicity of NbMoO4. Furthermore, the calculated density of states and experimental specific heat data from 2 to 20 K also confirm the metallic behavior. Our magnetization experiments indicate that the NbMoO4 exhibits paramagnetism. The valence states of Nb4+ and Mo4+ in NbMoO4 are revealed by the X-ray absorption spectroscopy.
