      abstract     = {The present work explores the effect of 120 MeV Au9+ ion
                      irradiation on the structural, electronic, and magnetic
                      behavior of CoFe2O4 (CFO) thin films, prepared by Pulsed
                      Laser deposition (PLD) technique. Grazing incidence X-ray
                      diffraction (GIXRD) analysis revealed that with increasing
                      ion fluences there is peak broadening and decrease in
                      diffraction intensity, which results reduction in
                      crystallite size and partial amorphization. X-ray
                      photoelectron spectroscopy (XPS) analysis showed an increase
                      in oxygen vacancy concentration, accompanied by partial
                      reduction of Co and Fe cations. A decrease in saturation
                      magnetization and enhanced coercivity has been observed with
                      increasing ion fluence, consistent with defect-induced
                      pinning. Law of Approach to Saturation (LAS) fitting on the
                      hysteresis curve has been carried out for the estimation of
                      the effective anisotropy constant (Keff), which provides the
                      quantitative evidence of irradiation-induced magnetic
                      anisotropy enhancement. X-ray magnetic circular dichroism
                      (XMCD) confirmed element-specific changes in magnetic
                      moments. The observed results are explained in terms of
                      disruption in superexchange interactions of
                      Co2+−O2−−Fe3+ after ion irradiation due to significant
                      modifications in the oxidation states of Co and Fe ions
                      within CFO thin films.},
