Large internal strains in very small iron oxide nanoparticles fabricated by spark discharge with electrodynamic acceleration of plasma jumpers

Iron oxide nanoparticles were fabricated by spark discharge method with electrodynamic acceleration of plasma jumpers. For different charging voltages of the capacitor from 8 to 15 kV the magnetite was the main phase represented by nanoparticles of 5-8 nm having large internal strains of the order of 25 x 10(-3).
