The magnetic and structural transformations in Tb/Fe multilayers irradiated with high energy Pb ions have been studied by 57Fe conversion electron Mossbauer spectrometry. Compositionally modulated amorphous FeTb alloy regions are formed at the interfaces in the vicinity of the ion path, accompanied by a loss of the perpendicular magnetic anisotropy. A phenomenological model, proposed earlier, has been used to explain the evolution of the magnetic anisotropy.
