ABSTRAKT

Complexes of magnetic nanoparticles with organic molecules are one of the materials studied today, since they have a number of unique properties. The method of monitoring the state of such complexes is poorly developed. In this paper, by monitoring ferromagnetic resonance and electron microscopic studies, the state of the nanoparticles is performed, which determines their magnetic interaction. It is shown that the organic substance forms a shell around the nanoparticles. As a result, the dipole-dipole interaction between the nanoparticles in the sample is reduced. It was found that the degree of magnetic interaction between nanoparticles was determined by the organic substance properties. The magnetic properties of nanoparticles can be controlled with the help of selection of the organic substance.
