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