Abstract

The novel synthetic procedure for wüstite nanoparticles with cubic shape was developed in the presence of a large amount of oleylamine and oleic acid against Fe precursor. The pretreatment under reduced pressure at 130 °C facilitated the formation of rather larger particles, 82 nm, by removing vapor during the reaction. The oxidation of FeO to Fe₃O₄ was precisely controlled so that the magnetic properties could be changed from paramagnetic to ferrimagnetic with the adjustment of the reaction time.
