Nanoparticles*

Abstract

Synthesis of materials in the nanosize such as nanoparticles makes it possible to control several properties such as their shape and stability. Magnetic nanoparticles, in particular, have a more advanced technology and more applications due to their physical and chemical properties compared to all other types of nanoparticles. There are many kinds of magnetic nanoparticles based on their different source such as metals, rare earth metals, oxidation of metallic nanoparticles, and magnetic alloys. The most commonly used metal oxides in synthesizing magnetic nanoparticles are Fe, Co, Mg, and Mn with their alloy compounds. Moreover, the main methods to synthesize magnetic nanoparticles are Co-precipitation, thermal ...
