Structural and magnetic properties of nanostructured iron oxide

Abstract

Nanostructured iron oxides are synthesized using ethylene glycol and polyvinyl pyrrolidone followed by calcinations. The X-ray powder diffraction measurement confirms the hematite phase of iron oxide. The synthesized hematite shows the Morin transition in the magnetization versus temperature (MvT) measurements. The nature of MvT depends on applied magnetic field. Magnetization versus magnetic field measurements confirm the antiferromagnetic behavior of hematite below the Morin transition and weak ferromagnetic behavior above the Morin transition.
