Abstract

Abstract A deactivable electronic article surveillance marker having elongated magnetically soft elements on a support in a criss-cross pattern with a plurality of magnetically semi-hard chips parallel to one another in rows with the rows being diagonally aligned relative to the elongated magnetically soft elements. In another embodiment, strips of magnetically semi-hard material are placed diagonally relative to the elongated magnetically soft elements. In both embodiments, the elongated magnetically soft elements can be in the form of a fiber.
