Superparamagnetic single phase zinc ferrite nanoparticles have been prepared by coprecipitation method at 20 °C without any subsequent calcination. The composition, crystallite size, microstructure and magnetic properties of the prepared nanoparticles were investigated using X-ray diffraction (XRD), field emission scanning electron microscope (FESEM), transmission electron microscope (TEM)...

We report on the enhance magnetic properties of synthesized Mg-Ferrite catalyst through microwave-assisted combustion route by making nanocomposite via Zn-ferrite. The gravimetric oil removal capability tests from water at room temperature were performed. Phase impurity and surface morphology which investigated with XRD analysis field emission- scanning electron microscopy, indicate that spinel...

Abstract We fabricated nanoparticles of Zn ferrite the chemical formula ZnFe2O4 using auto-combustion technique, and investigated their magnetic spin distribution frequency response to optical excitation. Optical absorption characterization were carried out in UV–Vis IR range, extended on low side down THz domain. The also characterized by X-ray diffraction force microscopy. dielectric constant...
