Magnetocaloric effect of FeNi magnetic nanoparticles obtained by the electrical explosion of wire technique

In this work the structure, magnetic properties and of the magnetocaloric effect of the large batches of magnetic FeNi nanoparticles were studied for selected compositions close to the invar. Nanoparticles were synthesized by the method of the electric explosion of wire using various technological parameters ensuring the difference in their dispersion parameters. The main variable parameter was the degree of overheating of the wire material. The use of different technological conditions for obtaining batches of nanoparticles ensured the difference in their dispersion parameters. Keywords: electric explosion of wire, magnetic nanoparticles, invar composition, magnetic properties, magnetocaloric effect.
