abstract = "We have performed specific heat measurements of a high-quality polycrystalline sample of CuV2S4. Two anomalies associated with charge density wave (CDW) transitions are clearly observed at T t1 = 92 K and Tt2h = 58 K. The anomalies at Tt1 and Tt2h show λ-type and spike-shaped behavior, indicating second and first order phase transitions, respectively. The electronic specific heat coefficient γ and the Debye temperature D are estimated to be 36 mJ/molK2 and 347 K, respectively, γ of CuV 2S4 is much larger than that of CuTi2S 4, whereas CuV2S4 exhibits a CDW gap at low temperature. This enhancement of γ is probably attributed not only to the electron-phonon interaction but also to electron-electron interactions.",
