Abstract :
Recently, we developed a system making magnetic Barkhausen emission measurements and performing multifunctional analysis of the results for the purposes of material characterization. The organization of this system, together with the procedures incorporated into the software, allows flexible control of applied fields and multivariate analysis of the Barkhausen signal emissions
