The effect of neutron irradiation on the Barkhausen noise in amorphous Fe40Ni40B40 alloys

  • Published:
Czechoslovak Journal of Physics B Aims and scope

Abstract

Theoretical expression for the power spectra of Barkhausen noise was used to obtain information on the dynamical properties of domain walls from the experimental spectra. It was shown that after irradiation the domain wall mobility increases due to the change of the effective mass of domain wallsm ef, damping constantβ and the spring constantα.
