Abstract

Un marcador para ser utilizado en una disposicion de vigilancia de artículos, disposicion de vigilancia que usa el marcador y método para hacer elmarcador, siendo particularmente un marcador de vigilancia electronica de artículos, deltipo armonico, que incluye un elemento activo alargado y delgadoy concentradores de flujo provistos en los extremos del elemento activo. Los concentradores de flujo tienen anisotropías magnéticas que están orientadas enforma perpendicular a la longitud del elemento activo. La orientacion de las anisotropías magnéticas en el campo de anisotropía de los concentradores deflujo estabilizan el umbral de conmutacion del elemento activo. El nivel de umbral de conmutacion puede ser controladovariando los parámetros tales comoel ángulo de las anisotropías magnéticas con respecto a la longitud del elemento activo, la fuerza del campo anisotropico de las anisotropíasmagnéticas, y la geometría del elemento activo y los concentradoresde flujo.
