Abstract
Three ways of nanoparticle production in the plasma of an arc initiated over aqueous salt solutions of metals (Ni, Cu) are discussed. It is found that the magnetic agglomeration of nanoparticles plays a key role in the ferromagnet. Jointed nanostructures measuring 50 × 50 × 200 nm, which are cemented by nickel being deposited during the nanoparticle growth, turn out to be single-domain. In contrast to nickel nanoparticles, copper ones (25–586 nm across) are sensitive to the electrolyte composition and parameters of the discharging capacitor.
