Abstract

The temperature dependent optical conductivity of β-Na_0.33V₂O₅ was studied. It was observed that both the midinfrared peak at 3000 cm^-1 and the observation of strong electron-phonon coupling support the picture that the charge carriers in βNa_0.33V₂O₅ should be regarded as small polarons. Furthermore, the strong Hubbard-type interactions brought about the independent behavior of the spin and charge channels at the metal-insulator phase transition.
