Fe(0) has important properties, for instance one of the largest intrinsic magnetic momentum (2.22 μB per atom). Moreover, Fe(0) is a very abundant and non-toxic material. Nevertheless, Fe(0) has a natural chemical sensitivity toward oxidation that is enhanced at the nanoscale (i.e., size < 100 nm), making the synthesis of Fe(0) nanoparticles challenging and consequently limiting the nanotechnological applications. This work focuses on the synthesis of Fe(0) nanoparticles with a small size of ~ 20 nm dispersed in a protective matrix of inert amorphous SiO2 at different Fe wt.%. The nanocomposites have been charactirezed by X-Ray Powder Diffraction and Vibrating Sample Magnetometer techinques at room temperature.

Abstract
Fe(0) has important properties, for instance one of the largest intrinsic magnetic momentum (2.22 μB per atom). Moreover, Fe(0) is a very abundant and non-toxic material. Nevertheless, Fe(0) has a natural chemical sensitivity toward oxidation that is enhanced at the nanoscale (i.e., size < 100 nm), making the synthesis of Fe(0) nanoparticles challenging and consequently limiting the nanotechnological applications. This work focuses on the synthesis of Fe(0) nanoparticles with a small size of ~ 20 nm dispersed in a protective matrix of inert amorphous SiO2 at different Fe wt.%. The nanocomposites have been charactirezed by X-Ray Powder Diffraction and Vibrating Sample Magnetometer techinques at room temperature.
