Pulsed laser ablation of solids in liquids has emerged in the last years as a reliable, rapid and ?green? method for preparing NPs in suspensions which, in general, are spherical in shape [1, 2]. In this work, we study the optical and magnetic properties of iron colloids produced by ultrashort pulse femtosecond laser ablation of a solid Fe target immersed in water and ethanol. The suspensions were analyzed with UV-visible Optical Extinction Spectroscopy (OES), Micro-Raman Spectroscopy and Vibrating Sample Magnetometer (VSM).
