Subsequent irradiation by 120 keV Ne<jats:sup>+</jats:sup> ions turns the thin film completely to the paramagnetic A1 phase. Repeated annealing at 300 °C for 60 min results in 100% magnetic B2 phase, i.e. a process that appears to be reversible at least twice. The A1 → B2 transformation takes place without any plane-perpendicular diffusion while Ne<jats:sup>+</jats:sup> irradiation results in significant interlayer mixing.</jats:p>
