FIELD: chemistry.
SUBSTANCE: magnetic nanocomposite has a "core-cladding-matrix" structure, where the core is iron nanoparticles with iron predominantly in the zero-valence state Fe0 (74.5%) and oxides thereof - 25.5%, the cladding which covers the nanoparticles is a ferrite, and the matrix is pyrocarbon in the sp2-hybridisation state. Total content of iron Fe0 in the obtained magnetic nanocomposite material is 31.01-38.25% and saturation magnetisation is equal to 3-59 Gs·cm3/g. A method of producing the magnetic nanocomposite is also disclosed.
EFFECT: thermal stability of the magnetic nanocomposite in an inert atmosphere and air; the magnetic nanocomposite is soluble in water and organic solvents, has super-magnetic properties and is electroconductive.
