Optical properties of pyrochlore oxides R2Mo2O7- delta (R: Sm, Gd, and Ho)
Abstract
The temperature dependence of the reflectance of the spin glass materials R2Mo2O7- delta (R: Sm, Gd, and Ho) has been measured for frequencies from 40 to 40 000 cm-1 The AC conductivity of Sm2Mo2O7- delta derived from Kramers-Kronig analysis, indicates a Drude-like behaviour as the temperature is lowered. Between 150 and 40 K the scattering rate shows a sharp drop which is attributed to the scattering of conduction electrons by short-range …
