Abstract

Activable and/or customized magnetic labels and technique of local annealing for obtaining them. The invention relates to the use of a new heat treatment procedure in the creation of activable magnetic labels including with specific signatures. It consists of producing crystallized areas in an amorphous material, so that magnetically hard areas (the crystallized areas) and soft areas (the amorphous areas) coexist within the same material, which can be used both in protecting objects (merchandise, books, etc.) and in the detection and authentication of official documents, banking items, etc.
