Structure and magnetic properties of Fe-Ni-Co alloy nanoparticles synthesized by an electrical explosion of twisted wires in an argon atmosphere

Abstract

Magnetic Fe-Ni-Co nanoparticles are synthesized by an electrical explosion of wires in an argon atmosphere. The average nanoparticle size is 66±1 nm. The nanoparticle show face centered cubic (fcc) and body centered cubic (bcc) structures. The observed grain size for the fcc phase is 64.1 and 44.8 nm for the bcc grains. The saturation magnetization and the coercivity are 82.3emu/g and 435 Oe, respectively. It is shown that the electrical explosion of wires can be used as a promising method for synthesizing the high-entropy alloy nanoparticles.
