Abstract
A method of synthesis of single-domain nanoparticles of (Fe1-xNix)Fe2O4 solid solutions of oxide ferrimagnetics (where х = 0÷1) has been developed. To suppress coagulation of particles during their synthesis, we used sodium chloride as an indifferent dispersant. After washing, the precipitate was recrystallized at 373 K for the time required for forming particles of a certain size. Then the precipitate was washed in acetone once more and kept in ethyl alcohol. The synthesized products are characterized by X-ray diffraction. Magnetic moment hysteresis loops were measured with use of a laboratory vibrating magnetometer at the room temperature. Demagnetized nanoparticles of (Fe1-xNix)Fe2O4 solid solutions were used as specimens. To suppress interparticle interactions, the nanoparticles were distributed in paraffin matrices. Materials with the known value of saturation magnetization (Ms) were used as the reference specimen: the tested specimen of nickel and the Fe3O4 (98 %) nanoparticles fabricated by "Nanostructured & Amorphous Materials Inc.", USA. The dependences of saturation magnetization and coercive force on nickel content have been studied. The synthesized material may be applied in micro- and optoelectronics, electrical engineering, biomedicine and other fields.
