For the first time, nickel-zinc ferrite nanopowder with the composition Ni0.2Zn0.8Fe2O4 was synthesized and physicochemically characterized by the method of thermal treatment of X-ray amorphous products of solution combustion method. It has been shown that ferrite formation occurs at a temperature of 465oC. A study of magnetic characteristics demonstrated that the resulting nickel-zinc ferrite nanopowder has a typical antiferromagnetic nature. The results obtained show the possibility of synthesizing X-ray amorphous combustion products of nanostructures with an average particle size of 24.8 nm, a degree of crystallinity of the order of 100%, and a specific surface area of 34.6 cm2/g using thermal treatment. Keywords: nickel-zinc ferrites, nanoparticles, solution combustion method, magnetic properties.
