Abstract
Using ferromagnetic resonance and electron microscopy, dispersing bulk nickel and its alloys in the course of interaction with the reaction medium (1,2-dichloroethane and hydrogen) accompanied by the intense growth of carbon nanofibres was studied. It is demonstrated that in all the cases the formation of rather uniform nickel nanoparticles occurs with the characteristic size of 200–300 nm. The efficiency of this method for studying the formation of nickel particles at the very initial stages of the reaction was demonstrated, including the induction period, when the use of electron microscopic studies is not efficient enough.
