Study of size dependent features of swift heavy ion irradiation in nanosized zinc ferrite

Physical Property Variation of Ferrite Nanoparticles under Heavy Ion Irradiation

“…Thus, it can be inferred on irradiating the spinel ferrite nanoparticles and thin films with swift heavy ions, deterioration of the crystalline structure, cation redistribution among lattice sites and amorphisation of the material takes place. This leads to a change in crystallite size after irradiation depending on the crystallite size of pristine ferrite as can be seen from Figure 11 (Singh et al, 2011;Singh et al, 2012b).…”

“…Not only their physical behavior but their utility for particular applications is influenced by the size of ferrite nanoparticles (Noreen et al, 2017;Li et al, 2019). Apart from size dependence, doping of various elements is also able to change in physical properties of ferrites (Dixit et al, 2012b). Doping of particular ions too influences the crystallite and cation inversion.…”

“…Thus, from several studies, it can be inferred that cation redistribution can take place on irradiation. Zinc ferrite nanoparticles annealed at 300, 500, 800, and 1000 o C were subjected to irradiation with 200 MeV Ag 15+ ions and studied bySingh et al (2012b) XRD analysis showed that the presence of impurity peaks after irradiation for samples annealed at 300 and 500 o C. However, nanoparticles annealed 800 and 1000 o C were in pure cubic spinel phase even after irradiation. Increased crystallite size was observed for all samples upto a certain fluence due to increase in local temperature as suggested byKaoumi et al (2008).…”

Effect of 200 MeV Ag16+ swift heavy ion irradiation on structural and magnetic properties of M-type barium hexaferrite

“…The material with swift heavy ion irradiation is an important tool which would be able to manipulate the properties of materials. This could provide an alternative to photons for presenting electronic excitations to material [5].…”
