Abstract
X-ray diffraction (XRD) was utilized to study the effect of 80 MeV 16O 6+ ion irradiation of the as-burnt ZnFe2O4 samples, prepared by sol-gel auto-combustion technique. The samples were irradiated at fluence: 1 × 1011, 1 × 1012, 1 × 1013, 1 × 1014 ions/cm2 to observe the effect of irradiation on structural properties and cationic distribution. XRD confirms the formation of single phase nanocrystalline cubic spinel ferrites with Scherrer’s particle diameter (D) ranging between 15.7 – 17.4 nm. Results very distinctly show the electronic energy loss induced changes in: - experimental and theoretical lattice parameter (aexp., ath.), tetrahedral and octahedral bond length (RA, RB), and shared tetrahedral and octahedral edge (dAE, dBE). The paper reports the generation of magnetic moment of Zn ferrite by swift heavy ion irradiation induced distortion at tetrahedral site.
