Preparation of magnetite nanoparticles and interpreting their magnetic behavior in wetting

Abstract

The wet chemical route of co-precipitation method is used to synthesize ultrafine magnetite for study. Using XRD, the estimated average size was ~24nm and confirmed the phase Fe₃O₄ with inverse spinal structure. The M-H loop of the Fe₃O₄ has investigated the magnetic entities and has confirmed the single domain nature. The paper has reported the magnetization saturation of Iron Oxide nanoparticles (IONs) increases with wetting. The effect of wetting has been discussed from the theoretical point of view. Dependency of magnetic property on the K, a and size for an effect was considerably analyzed in this study.
