Influence of annealing process on magnetic properties and Barkhausen noise of the Fe-W-B amorphous alloy

The study of structural changes followed by measuring of structure sensitive magnetic properties as the energy of total and stress induced anisotropy, the coercive field, the demagnetizing factor and the Barkhausen noise parameters of the as-cast and annealed Fe_81.4 W_2.6B₁₆ amorphous alloy was performed. The investigated structural changes were connected with the temperature range within which the Fe_81.4W_2.6B₁₆ amorphous alloy was characterized by the soft magnetic properties.
