Abstract

Unusually high coercivity at room temperature in CoFe₂O₄ nanoparticles was recorded. The samples were characterized by X-ray diffraction (XRD), transmission electron microscopy and Mössbauer spectroscopy. XRD analysis confirmed the presence of spinel CoFe₂O₄ phase only and the average grain size was evaluated to be 22 nm. Mössbauer studies showed that the sample consisted of superparamagnetic and single domain particles.
