DEPENDENCE OF MAGNETIC-PROPERTIES OF (FE50CO50)(78)SI7B15 AMORPHOUS WIRE ON THE DIAMETER

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