- Abstract
Nanoparticles of Al0.1Fe2.9O4 (AFO) were synthesized using a simple cathodic electrochemical deposition technique. Structural, morphological, and magnetic properties of AFO were systematically studied. The X-ray powder diffraction analysis indicated the formation of a sample in a single-phase cubic spinel structure. Morphological data analysis of the specimen showed that the AFO sample has a nanoparticle structure with an average diameter of ~ 8 nm. The magnetization measurement as a function of the magnetic field at room temperature confirmed the existence of a superparamagnetic behavior. Additionally, frequency dependence of AC susceptibility analysis indicated a weak interaction between AFO magnetic nanoparticles.
