Abstract
Results are presented from studying the effect ion-stimulated diffusion has on the profile of the distribution of chemical elements at a film–substrate interface during analysis with optical emission spectroscopy of a glow discharge. Sputtered films of iron garnets on a gadolinium–gallium garnet substrate before and after granulation via thermal annealing are investigated. The role of diffusion processes in shaping the distribution profile of elements at a film–substrate interface is shown. A technique is proposed for restoring the true shape of an interface profile without considering the effect the ion flux has on the film.
