Abstract
In this article, the power spectra of the Barkhausen noise of Ni1-xMnx is presented. The measurements were made in the ferromagnetic phase a t several temperatures and manganese concentrations in order to map th e effects of the degree of disorder and of the temperature on domain w all dynamics. Measurements in standard ferromagnetic materials were al so made to compare the dynamics in both cases.
