Local magnetic properties in amorphous magnetic wires

Abstract

Studies of local magnetic properties and near-surface micromagnetic structure of as-cast, mechanical polishing, and chemical thinned Fe- and Co-rich amorphous wires 125 μm in diameter with positive, negative and nearly-zero magnetostriction respectively were carried out employing magneto-optical Kerr effect. We can observe that the surface magnetization confirms to a big extent the behaviour related to the domain structure specific this type of materials. © 2010 IOP Publishing Ltd.
