Abstract

Third and fourth order spectral measurements of Barkhausen noise in single crystal 3% Wt. Si-Fe and previously measured Fe₂₁Co ₆₄B₁₅ samples showed striking differences. F_e_Si spectral measurements were consistent with independent pulse models, unlike data from amorphous Fe₂₁Co ₆₄B₁₅. Our measurements indicate that the variability of the high frequency exponent, which experimentally ranges between 1.5 and 2, is due to effects upon domain structure and other material properties
