“…In general, their results also showed that the total number of magnetic Barkhausen noise pulses increased with increasing grain size in commercial steel [5]. In subsequent work [6], the total number of the magnetic Barkhausen noises and, in addition, MAE pulses, has been found to increase with increasing grain size in decarburized steel, in agreement with [2][3][4][5]. This indicates that the Barkhausen activity of both 180° domain walls and non-180° domain walls (90° in steel) increases in general with increasing grain size in steels.…”

“…One class of recently developed instruments for the nondestructive measurement of grain size make use of the magnetic Barkhausen effect [2][3][4][5]. However, these are calibrated empirically, since no theoretical interpretation of the dependence of the magnetic Barkhausen effect on grain size has been given.…”

The Barkhausen-Spectra of pure iron have been measured for four recrystallized wire specimens of different grain size. The pulse size distributions show a strong dependence on this parameter. The number of the Barkhausen-pulses increases with decreasing grain size. The comparison of the spectra measured at an external field in the vicinity of the coercive force with those measured at a field where domain rotation begins shows that in the latter region the size and number of jumps is larger. Measurements of the counting rate of the Barkhausen jumps versus the external magnetic field show two maxima instead of normally one at the coercive force. This unusual behaviour could be explained with the successive change of Bloch wall types in certain sections of the hysteresis loop and their different interaction with dislocations.
