Abstract

Third and fourth order spectral measurements of Barkhausen noise in single crystal 3% Wt. Si-Fe and previously measured Fe21Co64B15 samples showed striking differences. FeSi spectral measurements were consistent with independent pulse models, unlike data from amorphous Fe21Co64B15. 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.
