Dependence of magnetic properties of (Fe/sub 50/Co/sub 50/)/sub 78/Si/sub 7/B/sub 15/ amorphous wire on the diameter

Abstract

The dependence of the magnetic properties of amorphous wire on the diameter have been investigated. The anisotropy constant, hence the internal stress, of the wire increases with the wire diameter. The size of the pinned reverse domain at the wire end increases with the wire diameter. Domain observation shows that irrespective of the change in the wire diameter, the domain structure basically consists of chevron domain layer sandwiched between the surface maze domain and the inner core domain.
