The stress dependence of Barkhausen noise in Fe81B13.5Si3.5C2 Metglas
TL;DR: In this article, the Barkhausen noise profile of Fe81B13.5Si3.5C2 Metglas changes from single to double peaks with applied tensile stress and the second harmonics during magnetization process under various stresses confirm that the single and double peaks on the BN profiles can be attributed to domain nucleation/annihilation.

Simultaneous observation of Barkhausen pulses and jumps in resistance fluctuations in ferromagnetic materials
TL;DR: In this article, an experimental setup which simultaneously registers induced Barkhausen pulses and short time variations in electrical resistance has been developed, which clearly shows the association between jumps in resistance and the dynamics of some magnetic domains.
