| description | A magnetic microwire for use in a magnetic tag attachable to a product is provided to enable authentication of the product, as well as the magnetic tag, a detector device and a system for product authentication utilizing the same. The magnetic microwire is a glass-coated amorphous magnetic microwire characterized by a large Barkhausen discontinuity and substantially zero or positive magnetostriction. The microwire is responsive to an external alternating magnetic field generated by the detector device to produce short pulse of magnetic field perturbations.
L'invention concerne un microfil magnétique destiné à être utilisé dans une étiquette magnétique pouvant être fixée sur un produit afin de permettre l'authentification du produit, ainsi que l'étiquette magnétique, un dispositif de détecteur et un système d'authentification de produits l'utilisant. Le microfil magnétique est un microfil magnétique amorphe enrobé de verre caractérisé par une grande discontinuité de Barkhausen et une magnétostriction sensiblement nulle ou positive. Le microfil réagit à un champ magnétique alternatif extérieur généré par le dispositif de détecteur afin de produire de courtes impulsions de perturbations de champ magnétique. |
