Abstract

The influence of magnetic field on phase composition, dispersivity, and magnetic properties of superfine powders fabricated by electric-spark dispersion technique in the liquid organic media is revealed. As shown, this effect is dependent on the working medium and external magnetic-field strength. As proposed, the change of specific saturation magnetization during superposition of external magnetic field can be conditioned by the induced superparamagnetism (or ferromagnetism) of carbon nanostructures.
