Abstract
(EN)
A method for manufacturing a magnetic wire is provided. The method for manufacturing a magnetic wire can comprise the steps of: forming a first preliminary magnetic wire by electrospinning a source solution comprising Fe; forming a second preliminary magnetic wire comprising Fe oxide by performing heat treatment on the first preliminary magnetic wire at a first temperature; performing heat treatment on the second preliminary magnetic wire at a second temperature, thereby forming a third preliminary magnetic wire in which Fe oxide is reduced; and performing, at a third temperature, heat treatment on the third preliminary magnetic wire in a source gas atmosphere comprising nitrogen, thereby forming a magnetic wire in which nitrogen penetrates the third preliminary magnetic wire.

L'invention concerne une méthode de fabrication d'un fil magnétique. La méthode de fabrication d'un fil magnétique peut comprendre les étapes consistant à : former un premier fil magnétique préliminaire par électrofilage d'une solution source comprenant du Fe ; former un second fil magnétique préliminaire comprenant de l'oxyde de Fe par réalisation d'un traitement thermique sur le premier fil magnétique préliminaire à une première température ; réaliser un traitement thermique sur le second fil magnétique préliminaire à une seconde température, formant ainsi un troisième fil magnétique préliminaire dans lequel l'oxyde de Fe est réduit ; et réaliser, à une troisième température, un traitement thermique sur le troisième fil magnétique préliminaire dans une atmosphère de gaz source comprenant de l'azote, formant ainsi un fil magnétique dans lequel de l'azote pénètre dans le troisième fil magnétique préliminaire.
