✦ Synopsis

The intermetallic ternary compounds of the type RMn 2 X 2 (R=Ca, La, Ba, Y and X=Si, Ge), crystallizing in the ThCr 2 Si 2 structure, show a large variety of collinear and noncollinear magnetic ground states (GS) depending on R and X and thus are good candidates for studying the dependence of the band structure contribution to the electronic transport on the different magnetic configurations. In this contribution we focus our analysis on LaMn 2 Ge 2 : A qualitative understanding of the change in the conductivities with the magnetic structure in this material is provided on the basis of its coherent electronic structure.

We study inelastic electron-ion scattering contributions to the thermoelectronic transport coefficients in dense plasmas. They are deduced from improved variational solutions of the Boltzmann-Ziman equation explained in this work. A new expression for the thermopower is proposed which is evaluated i
