Abstract

Optical conductivity spectra of La0.7-yPryCa0.3MnO3 were systematically investigated. For metallic samples, the spectral weight below 0.5 eV, whose magnitude can be represented by an effective carrier number N-eff(0.5 eV), increases as temperature becomes lower. Regardless of the Pr doping, all the measured values of N-eff(0.5 eV)/T-C fall into one scaling curve. This scaling behavior could be explained by the theoretical model by Roder et al. [Phys. Rev. Lett. 76, 1356 (1996)], whichincludes spin double exchange and Jahn-Teller lattice coupling to holes. [S0031-9007(98)07714-X].
