Abstract
Cet élément magnétostrictif auto-polarisant, utilisable dans un système électronique de surveillance d'articles (EAS), consiste en une bande en alliage amorphe possédant des particules cristallines d'un matériau magnétique à aimantation semi-permanente ou permanente réparties dans la masse de la bande en alliage. Les particules cristallines sont rendues magnétiques afin de polariser la bande en alliage amorphe de manière à résonner en réponse à un signal d'interrogation. On obtient ces particules cristallines par traitement thermique de la bande en alliage amorphe à une température supérieure à la température de Curie de l'alliage amorphe en présence d'un champ magnétique longitudinal. Cette bande en alliage est ensuite soumis à un recuit transversal à une température inférieure à la température de Curie de l'alliage amorphe de manière à obtenir une anisotropie transversale dans la masse amorphe de la bande en alliage. Une composition d'alliage préférée comporte du fer, du cobalt, du niobium, du cuivre, du bore et du silicium.
