Electric arc synthesis of magnetic Mn-Fe-C nanoparticles

Abstract

The aim of this research is to investigate the phase transformations and magnetic properties of nanoparticles formed during electric arc sputtering of composite Fe-Mn-C with subsequent annealing of the resulting composite in an oxygen atmosphere. As a result of the study, pure metals, mixed oxides, carbides, and carbon nanocomposites are synthesized. The magnetic susceptibility of Fe-Mn-C composites grows with an annealing temperature increase up to 600°C as compared to the iron-carbon system. The obtained methods and results can serve as a base for new synthesis techniques to obtain composite magnetic nanoparticles with a low carbon content.
