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.},
