Abstract
Within the frame of a Langevin description of Barkhausen effect (BE) phenomenology, a theoretical and experimental approach including the effect of longitudinal magnetic flux propagation is presented. Measurements of BE power spectra and of amplitude probability distributions of jumps are performed on amorphous ferromagnets either as-quenched or magnetic annealed. Theoretical curves are compared with experimental data and the microscopic theory parameters are discussed
