Abstract
Effects of isochronal and isothermal annealings on permeability, coercive field, field-induced anisotropy and electrical resistivity in Co58Fe5Ni10Si11B16 metallic glass pre-annealed at 743 K for 60 min were examined to clarify the correlation between thermal stability of soft magnetic properties and structural relaxation. It was found that both soft magnetic properties and electrical resistivity changed reversibly, depending on annealing temperature, and the values of activation energy for the changes in these properties were very close, lying in the range 1.8 and 2.0 eV. However, although the deterioration of soft magnetic properties was observed in the specimens annealed below the Curie temperature (T c), the resistivity changes occurred significantly even in the specimens above (T c), The results strongly suggest that the changes in soft magnetic properties are attributed to an anisotropic chemical short-range ordering (CSRO) among the cobalt, iron and nickel atoms, and the resistivity changes (structural relaxation) are mainly due to an isotropic CSRO.
