Abstract
In this paper 5 different samples of Ni-Cu-Zn nanoparticles (Ni0.8-xCuxZn0.2Fe2O4) with different compositions of x=0.2,0.4,0.6,0.8 synthesized through auto-combustion method using glycine as fuel and then structural, magnetic and optical properties of this samples investigated. Characterization of these samples done using XRD, FTIR, UV-Visible, SEM and SEM. XRD data proves existence of spinel structure for all samples. FTIR spectrum shows the existence of oxygen-metal M-O bond at tetrahedral and octahedral bonds. SEM images showed the semispherical shape of particles. Using UV-Visible spectrum we measured by increasing the amount of Cu dopant the gap energy of Ni-Cu-Zn nano particles decreases and also results of VSM showed that saturation magnetization decreases by increasing amount of Cu dopant.
