Alterations Appeared in The Hoping Length of Zinc Doped Nickel Ferrite System Driven by The Gamma Radiation Effect

A systematic investigation of structural, electrical, magnetic properties of Ni-Zn ferrite before and after gamma irradiation is carried out. Samples of spinel ferrite having the generic formula Ni1-xZnxFe2O4 with x = (0.0, 0.2, 0.4, 0.6, 0.8, 1.0) were prepared using the standard ceramic technique. The samples of Ni-Zn ferrite were irradiated with gamma rays using Co60 source at the laboratory. Gamma irradiation alters the structural properties of Ni-Zn spinel ferrites. The distance between magnetic ions i.e. hopping length at tetrahedral ‘A’ site and octahedral ‘B’ site is then studied.
