Vernadsky University popup.description2 A new way of producing ferrofluids including magnetite precipitation directly within aqueous -and- organic emulsion is proposed. For the first time ferrofluids to possess stronger magnetic properties based on cobalt-doped magnetite as magnetic filler have been synthesized. The solid-state composition materials with nanosized particle magnetic filler were produced. The investigation of the ferrofluids by magneto-metrical and X-ray methods had shown that the size of the magnetic particles corresponded to the range of several nanometers. The resonant behavior of Fe 3-x Co x O 4 based ferrofluids in the range of 10 - 40 MHz was discovered. Proton NMR technique in diluted ferrofluids had shown that the increase of magnetic filler concentration results in the increase of magnetic field inhomogeneity within the bulk of the sample.
