Research of the distribution function of ferromagnetic nanoparticles in colloidal solution on the values of their magnetic moments by method NMR

In the experimental study of the magnetization curves of the two magnetic liquids by the method NMR, it was found that the distribution function of nanoparticles on the values of the magnetic moments of P in the range of 4.5·10 -19-19 А·м 2 proportional to 1/ P. This result is consistent with the experimental distribution functions obtained by transmission electron microscopy at the sizes of nanoparticles more than 9 nm.
