- Abstract
Nanocrystals of maghemite (γ-Fe2O3) have been prepared at the interface of organic-aqueous layer by the reaction of ferric acetylacetonate in toluene with sodium hydroxide in aqueous solution. The nanocrystals of γ-Fe2O3 formed at the interface of the organic-aqueous layer have been confirmed by X-ray diffraction (XRD) pattern. The sample has been characterized morphologically by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and atomic force microscopy (AFM) techniques. Magnetic hysteresis loop and zero-field cooling measurements exhibited superparamagnetism behavior for γ-Fe2O3 nanocrystals.
