Local Structure and Magnetic Properties of Fe_(50)Cr_(40)Si_(10) Nanocrystalline Alloys

摘要

The structural and the magnetic properties of nanocrystalline Fe_(50)Cr_(40)Si_(10) alloys were prepared via mechanical alloying by using Fe, Cr, and Si elements with 1- to 24 hrs milling times. Structural analysis based on X-ray diffraction and Extended X-ray absorption fine structure spectroscopy. Concerning the magnetic behavior, the data obtained from a vibrating sample magnetometer at 300 K shows that both the magnetic saturation and the coercivity are dependent strongly on the milling time and the crystallite size. By adjusting the milling time, both appropriate structural transformation and magnetization values are obtained.
