Abstract :
Grain-oriented 3% Si-Fe strips were plastically strained up to 
%. The frequency spectrum 
of the Barkhausen noise was measured. From 
a mean Barkhausen volume veff is calculated. The noise and veff are diminished after plastic deformation mainly already in the region 
%, where the coercive field remains still constant, veff is related to a mean irreversible susceptibility, which is mainly determined by the hysteresis loop. By measurements of the correlation of the flux changes along the specimen a mean length of the Barkhausen volumes was obtained. Its diminution mainly causes the diminution of veff . The connection of the results with changes of the domain and dislocation structure is discussed.
