| The electronic structure and magnetic properties of La1-xCexPb3 and La1-xPrxPb3 are studied using the spin-polarized relativistic Korringa-Kohn-Rostoker coherent potential approximation method within the local spin density approximation. The calculated density of states at the Fermi level increases with the increase of the concentration. The dependence of spin and orbital magnetic moments of La1-xCexPb3 and La1-xPrxPb3 (0 < x < 1) on the concentration is also reported. The densities of states at the Fermi energy are dominated by Ce(Pr) 4 f5/2 and 4 f7/2 states. |
