Description
Summary:Electrical resistivity ρ, specific heat C , and magnetic susceptibility χ have been measured over 4.5 K - 300 K for the ternary molybdenum oxide TeMo 5 O 16 grown by a chemical vapor transport method. The temperature dependence of ρ and C shows an anomalous behavior around 170 K and a remarkable peak at 179 K, respectively. Furthermore, the magnetic susceptibility, subtracted by a Curie-Weiss component from the observed values, shows a decrease below 180 K. These results suggest that in TeMo 5 O 16 the charge density wave transition occurs at T c =179 K due to a reduction of the Fermi surface.
