| Abstract: | This research focuses on the formation and assessment of sol–gel auto-combustion-produced nanocrystalline Co0.40Ni0.6AlxFe2−xO4 (x = 0.00, 0.05, 0.1, 0.2) ferrites. The investigation explores the structural, morphological, electrical, dielectric, and magnetic characteristics of the spinel ferrites sintered at different temperatures (850 °C and 950 °C), with a specific emphasis on the impact of Al3+ substitution. A cubic single-phase spinel structure exhibiting excellent crystallinity and homogeneity is found across all samples, based on XRD evaluation. The nanoparticles had typical crystallite sizes between 40 and 48 nm and average particle sizes between 122 and 186 nm. Increasing Al3+ content resulted in increased nanoparticle porosity. According to infrared spectroscopy, the adsorption band v1 rose from 538 to 554 cm−1 whereas the v2 band dropped from 374 to 366 cm−1. With an increase in Al3+ content, the experimental magnetic moment (ηexp) and saturation magnetization (Ms) of the nanoparticles showed a notable upward trend. Furthermore, the samples sintered at 950 °C displayed higher AC resistivity, attributed to a reduction of the hopping electron within the grains. All of the ferrite nanoparticles under investigation also showed high coercivity values (1028.32–1222.76 Oe), designating them as ferrimagnetic materials and emphasizing the possibility for use in spintronics, high-frequency and microwave equipment like radar, antenna, and so on.
