Abstract

La invención se refiere a un marcador magnetomecánico para la vigilancia electrónica de artículos que comprende un elemento magenotoestrictorauto-polarizante. Dicho elemento se forma templando una cinta de material ferromagnético en presencia de un campo magnético aplicado en una direccióntransversal con relación al eje longitudinal de la cinta, y luego templando la cinta una segunda vez en presencia de un campo magnético aplicado en ladirección del eje longitudinal. La cinta templadados veces exhibe magnetización remanente a lo largo del eje longitudinal y tiene dominiosmagnéticos plurales situados a lo largo del eje longitudinal. La orientación de la magnetización de cada dominio está inclinada en ± 0° < 90° desdeel eje dela cinta alternando la dirección de inclinación de dominio a dominio.
