Abstract
Silver-substituted Fe–Ni nano invar alloy is a new and innovative field of research due to their interesting invar, magnetic and electrical properties. Due to these properties, Fe65Ni35−xAgx (x = 0.0, 0.5) alloys are studied comprehensively in this research work. The method used for synthesis of Fe65Ni35−xAgx (x = 0.0, 0.5) alloys is chemical reduction method in which cetrimonium bromide was used as capping agent, sodium borohydride as reducing agent, and hydrochloric acid to control the pH. X-ray diffraction, scanning electron microscopy, I-V characteristics, and vibrating-sample magnetometer were used for phase determination, surface morphology, electrical resistivity, and study of magnetic properties, respectively. Both alloys have face-centered cubic structure, lattice parameter is increased while crystallite size is decreased, agglomeration forms, electrical resistivity decreases, and saturation magnetization is increased by adding Ag content. Thus, properties of Fe–Ni invar alloys are improved by addition of Ag. Fe–Ni-Ag alloys have attractive magnetic properties as soft granular material and magnetoresistive materials particularly.
