Examination by a method of nuclear magnetic resonance of inside magnetic field change at formation of units in magnetite nanoparticle dispersion

The method for measuring of the intensity of local and medial magnetic fields inside magnetic nanoparticles dispersion is suggested. It is shown, that at the change of the structure occurring in the dispersion under the influence of an outside magnetic field, both intensities intensify synchronously, and the difference between them remains unchanged. Two hypotheses explaining this phenomenon are suggested.
