Nanostructure and chemical inhomogeneity in TbFe magneto-optical films

High spatial resolution chemical imaging results provided the first direct experimental evidence illustrating nanosegregation in thin films of sputtered Tb-Fe alloys. The observed chemical segregation appeared to result from the initial nucleation and growth of stable Fe-rich amorphous phase. The me...

Zusammenfassung:High spatial resolution chemical imaging results provided the first direct experimental evidence illustrating nanosegregation in thin films of sputtered Tb-Fe alloys. The observed chemical segregation appeared to result from the initial nucleation and growth of stable Fe-rich amorphous phase. The measured properties such as local fluctuation and magnetization reversal processes are explained on the basis of this chemical segregation effect.< >
