The spin dynamics in annealed ultra-thin Fe layers on GaAs(001) was analyzed using Brillouin light scattering (BLS). The samples used for investigation were grown by molecular beam epitaxy on GaAs(001). A critical annealing temperature existed at ≈225°C where Fe layer exhibited structural and magnetic behavioral change. The results show that annealing of room temperature deposited Fe layers to 300°C which had significant effect on magnetic properties and surface structure of Fe.
