Abstract

Magnetic nanoparticles of Cobalt Nickel Ferrite (Co1-xNixFe2O4) have been synthesized by the co-precipitation method with various concentrations of moles of Ni2+ as a constituent in Co1-xNixFe2O4 (x = 0.25, 0.50 and 0.75). The Co1-xNixFe2O4 structured shows the single phase of crystal was formed with a cubic spinel structure. The crystallite size estimated using the Scherer formula was found that the crystallite size decreased with increasing concentration of Ni2+. The samples with various concentration of Ni2+ showed coercivity and saturation magnetization was decreased by the increasing of concentration of Ni2+.
