摘要：

Concepts in fractal noises are applied to the ferromagnetic Barkhausen noise (BN). Various soft materials (amorphous alloy, 80-20 NiFe alloy, non-oriented FeSi) feature noise dimensions between 1.5 and 1.7. The scaling properties of the BN are examined (1/f power spectrum, Weierstrass distribution, wavelet expansion). It is argued that the hierarchical structure of the BN reflects scaling, avalanche-like irreversible processes.
