The study of the infrared spectrum of a magnetic nanoparticles in a magnetic field structure

The action of a magnetic field on the magnetite nanoparticles colloidal solution leads to the appearance of an oscillatory rotational absorbtion specrum of infrared radiation with an energy of lower vibration levels close to exchange interaction energy in the domains of the nanoparticles. The effect can be explained by the conversion of photons energy into the energy of vibrations, which break off the domain structure of magnetite above the Curies temperature. The depth of the potential well, defined by bringing together the vibration levels, is more than Curies temperature in energetic units. That's why it is possible to suppose tunnel effect оr a vibration and rotational levels superposition as a reason of the domain destruction.
