The measurement of magnetic moments of ferromagnetic nanoparticles by the positions of the lines of infra red spectra of a magnetic liquid in a magnetic field

The investigation infra red spectra of a magnetic liquid in a magnetic field showed, that a rotation lines were shifted, when a magnetic field was changed. We determined the magnetic moments of nanoparticles that are equal tu 1.0·10-19, 3.2·10-19, 8.7·10-19Am2. Magnetic moments, which were measured by electromagnetic methods, were the average meanings of discrete magnetic moments.
