Abstract

The nanocrystalline powders of Mn50Ni41Sn9 were prepared by ball milling using a PM 200-type RETSCH planetary ball mill. The morphological, microstructural, and structural characterizations of the nanostructured powders were carried out by scanning electron microscope, x-ray diffraction, first using the Williamson–Hall relation for the refinement of the diffraction peak profiles. The high-temperature thermal and magnetic properties of nanocrystalline alloy Mn50Ni41Sn9 were characterized at different temperatures using a vibrating sample magnetometer; differential scanning calorimetry was used to determine the transformation temperature and thermodynamic values in the Mn50Ni41Sn9 alloy.
