Resumen
Relaxation phenomena related to domain structure dynamics in amorphous ferromagnetic Fe64Co21B15, and Co77B23 samples were studied by time-resolved three-dimensional neutron depolarization and a conventional magnetic induction technique. Different initial domain structures were induced either by applying external stresses or by stress annealing. A theoretical model was developed to describe the observed time dependence of neutron depolarization upon passage through such samples. It is shown that the domain structure approaches the equilibrium state with stable domain wall positions at a rate that depends essentially both on the sample composition and on the induced magnetic anisotropy.
