COHESIVE AND SUPERCONDUCTING PROPERTIES OF LA-IN COMPOUNDS FROM ELECTRONIC-STRUCTURE CALCULATIONS

A recently developed method by Williams et al. to calculate the electronic structure and cohesive properties of metallic compounds is applied to study the intermetallics La3In, LaIn and In3La. Local-partial as well as total densities of states are given. The lattice constants, bulk modulus and heats of formation are obtained and discussed. The latter is decomposed into site and angular momentum contributions. The band-structure results are applied to calculate the electron-phonon interaction and the superconducting transition temperatures are obtained. © 1979 Springer-Verlag.
