In this study, Ni0.6Zn0.4Al0.5Fe1.5-xNdxO4 ferrite samples with varying Nd3+ concentrations were synthesized using the sol-gel method. The effects of Nd3+ doping on the structural, magnetic and spectroscopic properties were investigated. The results showed that an increase in lattice constant and porosity occurred with increasing Nd3+ concentration, while the magnetic properties such as saturation magnetization, coercivity and remanence magnetization decreased.
Ni0.6Zn0.4Al0.5Fe1.5-xNdxO4 ferrite samples, with x = 0.00, 0.05, 0.075 and 0.1, were synthesized using the sol-gel method. The effects of Nd3+ doping on the structural, magnetic and spectroscopic properties were investigated. XRD Rietveld refinement carried out using the FULLPROF program shows that the Ni-Zn ferrite retains its pure single phase cubic structure with Fd3m space group. An increase in lattice constant and porosity happens with increasing Nd3+ concentration. FTIR spectra present the two prominent absorption bands in the range of 400 to 600 cm(-1) which are the fingerprint region of all ferrites. The change in Raman modes in the synthesized ferrite system were observed with Nd3+ substitution. The magnetization curves show a typical transition, at the Curie temperature T-C, from a low temperature ferrimagnetic state to a high temperature paramagnetic state. The saturation magnetization, coercivity and remanence magnetization are found to be decreasing with increasing the Nd3+ concentration.
