摘要：

The multilayer of approximate structure MgO(100)/[(Fe51Rh49)-Fe-n(63 angstrom)/(Fe51Rh49)-Fe-57(46 angstrom)](10) deposited at 200 degrees C is primarily of paramagnetic A1 phase and is fully converted to the magnetic B2 phase by annealing at 300 degrees C for 60 min. Subsequent irradiation by 120 keV Ne+ ions turns the thin film completely to the paramagnetic A1 phase. Repeated annealing at 300 degrees 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+ irradiation results in significant interlayer mixing.
