Swift heavy ions (SHI) irradiation is a unique and effectual tool, which is recognized to produce controlled defects (point/cluster and columnar), structural disorder, stress, and phase transformations in the thin films and to modify the physical properties of materials. In addition, it is well known that the distribution of the magnetic moments in the films depends on the competition among magnetocrystalline anisotropy energy (Ek), demagnetization energy (Ed) and magnetoelastic energy (Eλ), and the effective magnetic anisotropy (Eeff) is by the above components interaction results. So, can we modify Eeff by SHI irradiation?
