Abstract

Alternating current Joule heating is explored to produce magnetic wires consisting of two different magnetic phases, one soft, with coercivities of the order of few A/m, and other harder, with coercivities around 10 kA/m. The effect of current frequency and intensity in the formation of the two-phase composite material is investigated. Although the two phases are formed due to different loss parameters along the wire length (basically due to thermal contacts), there is also an important influence of the skin effect
