The surface magnetism investigation of FeSiB amorphous thin films obtained by evaporation technique

Using magneto-optical Kerr effect the surface magnetic properties of as-deposited and thermal/magnetic annealed Fe77.5Si7.5B15 amorphous thin films obtained by evaporation technique are investigated. The minimum value of the coercive field for the as-deposited samples was about 350 A/m, while after magnetic annealing its value becomes about 18 A/m.
