A. Javed, T. Szumiata, A. Sarwar and T. Fatima, Structure and Mössbauer spectroscopy studies of Ni 0.5Zn 0.5Nd xFe 2− xO 4 (0.00 ≤ x ≤ 0.10) ferrites, Mater. Chem. Phys., 2018, 221, 99–107 CrossRef.Ni 0.6Zn 0.4Al 0.5Fe 1.5− xNd xO 4 ferrite samples, with x = 0.00, 0.05, 0.075 and 0.1, were synthesized using the sol–gel method. The effects of Nd 3+ 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 Fd m space group. An increase in lattice constant and porosity happens with increasing Nd 3+ 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 Nd 3+ 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 Nd 3+ concentration. Palazov, A., Chang, C. C. & Kokes, R. J.
