Abstract : The Barkhausen noise energy per cycle Ef of non-oriented silicon steel sheets was measured as a function of the frequency fm of the magnetizing field . As fm increases, Ef first grows exponentially, then increases more gradually like f2m. This shows that the tendency to clustering of Barkhausen pulses is enhanced by increasing fm. The results are discussed in terms of the distribution function of time intervals between pulses.
