20 Oct 2000 | | Journal: | PRB 63, 121102 (2001) | | Subject: | Strongly Correlated Electrons | cond-mat.str-el | | Abstract: | We present the measurements of the polarized optical spectra of NaV2O5 and LiV2O5. In an energy range from 0.5 to 5.5 eV we observe similar peaks in the E parallel a spectra of LiV2O5 and NaV2O5, which suggests similar electronic structure along the a axis in both materials. On the other hand, we find an almost complete suppression of the peaks in sigma_b of LiV2O5 around 1 and 5 eV. We attribute this suppression to the charge localization originating from the existence of double-chain charge-ordering patterin in LiV2O5. | | Source: | arXiv, cond-mat/0010327 | | Services: | Forum | Review | PDF | Favorites | |
