Abstract

The calculations of the electronic and the optical properties of CeSb and LaSb, using the full potential augmented plane wave (FP-LAPW) method including spin orbit coupling within local spin density (LSDA) approximation as implemented in WIEN2K code have been performed. The reflectivity and the real part of the optical conductivity of CeSb and LaSb have been calculated. The real part of the optical conductivity of these compounds is deduced from Kramers-Kronig transformation. The calculated spectra of the real part of the optical conductivity and reflectivity of LaSb and CeSb are in the agreement with the available experimental data. Our calculations give the value of specific heat constant of CeSb and LaSb 23.4 mJmol ^-1K ^-2 and 0.37 mJmol ^-1K ^-2, respectively, which are very close to experimental value.
