Abstract

The Barkhausen effect produces a sequence of magnetization avalanches during smoothly changing magnetic fields. The avalanches are the result of the jerky motion of domain walls under presence of pinning forces. The Barkhausen noise avalanches follow a power law distribution for very slow excitations for large samples. Under non ideal conditions, the exponent and cut-off parameters will depend on the conditions of the experiment [1]. In this paper we present results for the effect of excitation frequency and amplitude, sample geometry and the pick-up coil parameters on the Barkhausen noise parameters.
