概要

The band structures of AFe. (A= Mo, Hf, Ta, W) were calc;ulated to examine the in-fluence of the atom A on the electronic structures and the magnetic properties. Theband structures are essentially unaffected by the difference in the kind of d bands ofthe atom A. The hybridization between d states of A and Fe becomes stronger with in-creasing the number of valence electrons of the atom A and affects the DOS curves ofFe(2a) and Fe(6#) around the Fermi level which are closely related with the magneticproperties for the C14 compounds. However, since the variation of the electronicstructure with the change of the atom A is not so drastic, we can roughly guess themagnetic properties of the C 14 compounds with the rigid-band-model.
