Magnetic and Structural Studies of the Verwey Transition in Fe₃-δO₄ Nanoparticles

Abstract

The Verwey transition in Fe 3-δO 4 nanoparticles was investigated to study the magnetic and structural properties. It was shown that charge ordering of Fe 3+ and Fe 2+ and lattice distortion are not observed below the Verwey transition temperature in the stoichiometric and cation-deficient magnetite. It was found that as the cation vacancy increases, the lattice parameter and the Verwey transition temperature decrease. The results show identical XRD patterns indicating that all samples are single phase and have a cubic structure at room temperature.
