The influence of morphology, conditions of production and external effects on nanoparticles’ (in terms of iron) dielectric properties

It was shown that the complex research of iron nanoparticles properties by different methods, supplemented each other, permit to receive the data about the interior sizes of nanoparticles, a number of physical properties of particles, their dependence on frequency and changes produced by various influences. It was found that the conductivity of nanoparticles changed under the square dependence $\sigma$ = $\sigma_o$ $\omega_2$.
