Properties of manganese ferrite-paraffin composites

Abstract

Manganese ferrite (MnFe2O4) nanoparticles were dispersed in paraffin and the physical properties of this composite were investigated by X-ray diffraction (XRD), ferromagnetic resonance (FMR), vibrating sample magnetometry (VSM), field cooled (FC) and zero field cooled (ZFC) curves and Mössbauer spectroscopy. The results showed that dispersion in moderate quantities of paraffin significantly increases the crystallite size, the absolute value of the anisotropy field, the saturation magnetization and the blocking temperature of the nanoparticles, a result that may be of interest for practical applications of the composite.
