Iron oxide nanoparticles were prepared by Nd:YAG laser ablation in water under effect of an external magnetic field. The X-ray diffraction analysis of iron oxides nanoparticles showed that the synthesized nanoparticles were crystalline magnetite Fe 3 O 4. The intensity of the x-ray peaks increased after applying the magnetic field. Field emission scanning electron microscope (FE-SEM) showed that the average grain size of the nanoparticles was decreased from 85nm to 45nm and the particles agglomeration has been decreased after applying the magnetic field. The energy gap increased after applying the magnetic field during the ablation process. Raman spectroscopy of the iron oxide nanoparticles showed formation of T 1g and A 1g modes.
