Extended properties of magnetic spins of zinc ferrite nanoparticles in the THz frequency range

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 was calculated both bandgap, dispersion energy oscillator strength from data based single model. measured absorption, transmission reflection spectra wavelength range 200 800 nm, refractive index, extinction coefficient. band gap found be 1.14 eV oscillating dipole determined 6.94 eV. study shows that coordination number a metal complex symmetrical arrangement play an important role determining nanoparticle properties.
