Abstract

Local structural and magnetic characterization of (Ni0.5Al0.5)100-xCx (x = 0, 10, 30, and 50 at. %) nanocrystalline alloys which were prepared by mechanical alloying (MA) technique at 12 hrs milling time, have been carried out in detail. The nanocrystalline size and shape were examined using scanning electron microscopy (SEM). The effect of carbon on structural properties has been investigated using x-ray diffractometer (XRD) and extended x-ray absorption fi ne structure spectroscopy (EXAFS), whereas magnetic properties was examined by vibrating sample magnetometer (VSM). All the samples revealed nanocrystalline alloys. The maximum magnetic saturation (Ms) at about 0.7 emu/g and the minimum coercivity (Hc) at about 135 Oe would be found for 10% carbon content.
