In this work, the effect of bombardment with high-energy ions on the parameters of magnetic tunnel junctions based on CoFeB / MgO, such as magnetic anisotropy, magnetoresistance, and the damping coefficient of magnetization precession, is investigated. The modeling of the ferromagnetic resonance spectra was carried out within the framework of the Smit-Beljers and Landau-Lifshitz-Gilbert formalisms. The ion fluence limit is established, below which a controlled modulation of the magnetic anisotropy is achieved while maintaining a high tunneling magnetoresistance and stable magnetic configuration of the transition
