Zusammenfassung:Summary form only given. The Fe/sub 2/Nb intermetallic compound crystallizes in the MgZn/sub 2/ structure ( hexagonal Laves phases) and its magnetic properties was studied extensively. We have simulated the Fe-Al-Nb alloys by the Fe substitution for Al atoms in the (0,0,0) and (0,0,0.5) sites of the Fe/sub 2/Nb phase, and its magnetic behavior was studied using the linearized augmented plane waves (LAPW) method, code Wien (97). The spin magnetic moments are 1.53 /spl mu//sub B/ for the Fe atom in the site with 6 Fe neighbors, -0.012 /spl mu//sub B/ for the Al atom with 2 Al neighbors and -0.048 /spl mu//sub B/ for the Nb atom with 4 Nb neighbors. In the metal, the spin magnetic moment is 2.31 /spl mu//sub B/ for the iron atom. The authors show the magnetic behavior of the material by the change observed in the total density of states of spins up and spins down, and a magnetic moment measurement of this compound.
