Abstract

We investigate the role of grain size in the magnetization process of nonoriented 1.7% Al 1.9% Si Fe steels by measuring the power spectrum and the amplitude probability distribution of the Barkhausen noise. Experiments refer to single strips of variable grain size (0.03 mm&lt;s&lt;0.27 mm) and are made under controlled values of magnetization rate and permeability. We also study the propagation along the specimen of individual Barkhausen reversals at very low magnetization rates (3×10−4 T s−1). The data are interpreted in the frame of a theory recently proposed by the authors, which connects the Barkhausen effect to the statistical properties of the random local coercive field experienced by a moving domain wall.
