Abstract
We report on the optical properties of the hole-doped manganites La0.7Ca0.3MnO3 and La0.7Ca0.3MnO3. Transmission and reflection of thin films are measured in the infrared at temperatures from 10 - 150 K using Fourier-transform spectroscopy. The scattering rate and optical mass are obtained by fitting the far-infrared transmission to a Drude model. The scattering rate shows a T2 dependence with temperature. The optical mass enhancement differs only slightly from specific heat results. In addition, we compare the infrared spectral weight to band structure calculations [M. Quijada et al., Phys. Rev. B 58, 16093 (1998)].
