摘要：

The electronic structure of iron-palladium alloys are studied using the self-consistent linear muffin-tin orbital (LMTO) method. In particular, three compounds are analyzed, namely, Pd3Fe, PdFe, and PdFe3 and their stability investigated with respect to the iron concentration. Results are obtained from ferromagnetic calculations for each alloy. Our discussion on internal excess energy shows the PdFe3 ordered structure to be at best metastable with respect to its disordered alloy, while Pd3Fe and PdFe are stable compounds. Results for PdFe3 show a collapse of its magnetic moment as a function of the lattice parameter.
