NiIn_xFe_2−xO₄ (x=0.0, 0.1, 0.2, 0.3, 0.4) ferrite nanoparticles have been synthesized by sol-gel autocombustion technique. The effect of Inp>3+p> substitution on the structural and magnetic properties of nickel ferrite has been analyzed by X-ray diffraction (XRD), Fourier transform infrared spectra (FTIR), Field emission scanning electron microscopy (FESEM) and Vibrating sample magnetometer (VSM). The XRD results confirmed the formation of single cubic spinel phase for pan id="mmlsi0001" class="mathmlsrc">pan class="formulatext stixSupport mathImg" data-mathURL="/science?_ob=MathURL&_method=retrieve&_eid=1-s2.0-S0921452616304409&_mathId=si0001.gif&_user=111111111&_pii=S0921452616304409&_rdoc=1&_issn=09214526&md5=014ece51255d2d9145c91c5f67d373f4" title="Click to view the MathML source">0≤x≤0.3pan>pan class="mathContainer hidden">pan class="mathCode">$0\le x\le 0.3$pan>pan>pan> and the appearance of secondary phase of In₂O₃ for x=0.4. The lattice parameter increases (from 8.3152 to 8.4336 Å) with indium content. The FTIR results illustrated that the absorption intensity of peak at about 594 cmp>−1p> increases with increasing the Inp>3+p> ions. The saturation magnetization increases and then decreases while the coercivity decreases along with Inp>3+p>substitution. The maximal saturation magnetization emerged at the composition of NiIn_0.2Fe_1.8O₄ (42.111 emu/g).
