摘要

It was shown that the action of a DC discharge (discharge current is 50 mA) in air at atmospheric pressure on a mixture of iron nitrate (III) and nickel nitrate (II) salts located on the cathode leads to the formation of nickel ferrite. The composition of the ferrite (Ni1.43Fe1.7O4) and the size of the crystallinity region (~ 29 nm) were determined using XRD and EDX analysis. It was found that the synthesized substance is a soft magnetic material with a saturation magnetization of 27 emu/g (293 K), a BET specific surface area of 21 m2/g, and a pore volume of 0.044 cm3/g.
