Methods of research: atomic force microscopy, magneto-optical spectrometry, structural and electrical conductivity studies, magnetometry. This report presents the results of studies on the influence of electromagnetic field on water, on liquid crystal samples with magnetic nanoparticles, on the phase structure and magnetic characteristics of Sr2FeMoO6- nanopowders and on the magnetic susceptibility of magnetic nanoparticles of Fe3O4 and NiFe2O4 to the structure and magnetic characteristics of Ni81Fe19 nanocrystalline films. It is shown that under the influence of an electromagnetic field there is a water purification. In liquid crystals with magnetic nanoparticles, the magnetic field causes a polarization plane to rotate over an angle of more than 10 degrees, while in the nanosized Sr2FeMoO6- magnetic field with induction greater than the anisotropy field stimulates the transition from the metastable state to a stable superparamagnetic state. A constant magnetic field reduces the magnetic susceptibility of high-frequency magnetization of Fe3O4 and NiFe2O4 nanoparticles. In nanocrystalline Ni81Fe19 films under the action of nanosecond laser pulses the surface roughness decreases and their magnetic characteristics are improved. According to the results of researches, the Ukrainian patent for invention №114105 was received on the device for water purification. Product Description popup.authors Дереча Д.О. Коростель А.М.
