Abstract
UN MARCADOR (10) PARA SER UTILIZADO EN SISTEMAS DE VIGILANCIA DE ARTICULO ELECTRONICO DE TIPO MAGNETICO CONSTA DE UN SUSTRATO (12) SOBRE EL QUE SE DEPOSITAN VARIAS PELICULAS FINAS MAGNETICAS DE BAJA FUERZA COERCITIVA Y ALTA PERMEABILIDAD (14, 18, 22, 26, 30, 34) ESTANDO CADA UNA DE ELLAS SEPARADA DE UNA PELICULA FINA MAGNETICA ADYACENTE MEDIANTE UNA PELICULA FINA NO MAGNETICA (16, 20, 24, 28, 32). CADA UNA DE LAS PELICULAS MAGNETICAS TIENE SUSTANCIALMENTE LA MISMA PERMEABILIDAD Y FUERZA COERCITIVA Y LAS PELICULAS NO MAGNETICAS TIENEN UN GROSOR TAL QUE PERMITEN EL ACOPLAMIENTO MAGNETOSTATICO AL TIEMPO QUE INHIBE EL ACOPLAMIENTO DE INTERCAMBIO. SEGUN ESTO, TODAS LAS PELICULAS FINAS MAGNETICAS SE CONVIERTEN EN UNA ENTIDAD UNICA Y PRODUCEN UNA RESPUESTA AGUDA, FACILMENTE DISTINGUIBLE.
