Abstract 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.

The work is devoted to the discussion of magnetic dynamics features in mesoscopic magnetic structures under the action of spin transport and spin-torque transfer in the nanopillar structures. Tunneling magnetic structure consisting of autoemission cathode and patterned magnetic anode is considered. Main bifurcation changes in the states of a dynamical system, that models mesoscopic structure, are discussed for varied spin polarized current and an external magnetic field.
