Laser synthesis of magnetic iron oxide nanopowders

Abstract

Magnetic iron oxide nanopowders are synthesized by the laser ablation of a target made of a coarse Fe 2 O 3 powder. The geometric characteristics of the nanopowders and their yield are studied over a wide air pressure range ((1-34) × 10 4 Pa) in an evaporation chamber. The phase compositions of the nanopowders and the conditions under which their chemical composition is closest to magnetite Fe 3 O 4 are determined. The specific saturation magnetization and the coercive force of some iron oxide nanoparticles are measured.
