Calculation of Magnetic Properties and Analysis of Valence Electronic Structures of LaT₁₃_-<i>_x</i>Al<i>_x</i> (T = Fe, Co) Compounds

Abstract

The magnetic properties of the LaCo 13- x Al x and LaFe 13- x Al x compounds have been calculated, and the valence electronic structures of these compounds have been analyzed using empirical electron theory. In general, the calculated results agree with those of the experiments. Analysis of the electronic structures reveals the relation between the electronic structures and magnetic properties of these compounds.
