Internal stresses and Barkhausen noise of Fe80B20 amorphous alloy treated by annealing and hydrogenation–dehydrogenation processes

Internal stresses as a consequence of structural changes of the Fe80B20 amorphous alloy during annealing and hydrogenation–dehydrogenation processes were observed by structurally sensitive properties as a stress induced anisotropy, a coercive force, a demagnetizing factor and the Barkhausen noise parameters.
