Abstract
|
|
|
|
The Fe_(2-x) Ge(0≤ X ≤ 0.32) intermetallic compound, fabricated by the melting method, have been studied by the X-ray diffraction in order to investigate the crystal structure. Iron atoms are located at all three sites, 2(a), 2(d) and 2(c) of the B8_(2) type structure. From the disagreement factor of the X-ray peak intensity, it is found that the iron atoms are located mainly at 2(a) site and Ge atoms are at 2(c) site and the lattice parameters of the B8₂ type structurre are a_(o)=3.994569∼4.05824 Å and c_(o)=4.990562∼5.037881 Å. And we conclude that the vacancies are randomly distributed in the unit cell.
