Abstract :
Iron oxide magnetic nanoparticles were obtained by a highly productive laser target evaporation technique while varying type and pressure of the working gas and laser pulse duration and average output power. Water-based suspensions stabilized with sodium citrate were prepared. Synthesis in air, 100 μs laser pulse duration, and 200 W average power resulted in disaggregated superparamagnetic nanoparticles with an average diameter of 9.9 nm.
