The Effect of Disordering on Magnetic Properties of Fe-Al Alloys
The results of magnetometric, Mössbauer and XMCD (X-ray Magnetic Circular Dichroism) studies of B2 or DO3–type ordered (25 to 35 at.%Al) and disordered by mechanical activation (35 to 60 at.% Al) Fe-Al alloys are considered. For the description of magnetic characteristics of the studied alloys the validity of local magnetic moments models is discussed. The models suppose that Fe atom local magnetic moments are collinear with magnitude and direction depending on the number of Al atoms in the Fe nearest neighbourhood.
