Abstract :
Magnetic Barkhausen noise measurements were performed on various samples of 3% Si steel laminates in order to clarify the relationship between the domain structure, grain orientation, and power losses. The total Barkhausen noise power has been measured versus applied field. The statistical parameters characterizing the Barkhausen noise were related to macroscopic material properties. The results obtained show that a correlation exists between the Barkhausen noise power and the total power losses. This makes it possible to connect the crystallographic structure to the magnetic behavior of grain oriented materials at both microscopic and macroscopic levels
