Radiation Stimulated Permanent Alterations in Structural and Electrical Properties of Core-Shell Mn-Zn Ferrite Nanoparticles

Abstract: A series of core-shell type nanoparticle samples of MnxZn1-xFe2O4 were prepared by auto-combustion technique with x=0.3, 0.5, 0.7, 1.0. Subsequent to the structural and electrical property investigation the samples were irradiated with gamma radiation for different time intervals using 60Co source. A significant decrease in lattice parameter and particle size was observed in gamma irradiated samples. Electrical resistivity of irradiated samples was found to decrease with the increase in γ-radiation dose. Frequ… Show more

“…Typical TEM images of spinel ferrite NPs prepared by the most common routes are shown in Figure 1. [92]; or other mixed ferrites NPs [93,94]. A natural core-shell structure is obtained for magnetite NPs due to topotactic oxidation to maghemite, which is mirrored, for example, in varying heating efficiency [95].…”

“…Moreover, with increase in amount of CSNs increase in σ ac is observed which may be assigned to fine dispersion of CSNs inside complete polymer and a fine interface adhesion between CSNs and PVA matrix. 40 In addition to this, CSNs forms seamlessly linked network between HOMO-LOMO due to development of newly localized electronic states arranging a swift path for transfer of charge carriers. 41 It is also observed from Fig.…”
