Nonaqueous Sol–Gel Synthesis of Magnetic Iron Oxides Nanocrystals

Abstract

Benzyl alcohol route, starting form Fe ( III ) acetylacetonate, was applied to obtain crystalline magnetite nanoparticles. In particular, the effect of synthesis parameters (time and temperature) and use of SOCl 2 on the physical and magnetic properties of the so‐obtained powders were evaluated. By means of this approach, monocrystalline magnetite particles with size ranging from 5 to 15 nm were obtained.
