    Abstract:

    Swift heavy ion (SHI) irradiation of materials is very powerful tool to modify various properties of the materials and it provides an alternative path to photons for providing electronic excitations in to the materials [1-4]. Cobalt ferrite (CoFe2O4) samples were prepared using SHS route and irradiated with 200 MeV Ag+16 ions using the 15 UD pelletron tendem accelerator at IUAC, New Delhi, India.
    Prepared cobalt ferrite samples were irradiated at difference fluences from 1× 1013 to 1×1012 ions/cm2. Pristine as well as irradiated CoFe2O4 samples were characterized using FTIR, XRD and SEM. FTIR spectra of all samples show two bands at 410 cm-1 and 540 cm-1. There is no change in peak position but the intensity of peak decreased and broadness increased as ions fluencies increased from 1×1012 ions/cm2 to 1 × 1013 ions/cm2. XRD peaks show that after irradiation (1 × 1013 ions/cm2) intensity as well as FWHM of all peaks were increased, which confirmed structural modification. There was significant change in surface morphology after SHI irradiation. Pristine Cobalt ferrite sample shows agglomerated clusters of non-uniform grains of different size, while irradiated sample show relatively better morphology. SEM images analysis supports XRD results
