Influence of Heat Treatment on the Magnetism of Carbon Coated Iron Nanoparticles

Article Preview

Abstract:

Magnetism Carbon coated iron nanoparticles were produced by DC carbon discharge method .The structure , size distribution , phase composition and magnetic properties of the particles were investigated using TEM , XRD and VSM. The result s show that the core of t he particles is iron , and the shell of the particles is onion shaped carbon. The hysteresis curves of the particles show acharacteristic of superparamagnetic material.
