Abstract

Patente de Invenção: <B>"MARCADOR DE VIGILâNCIA ELETRôNICA DE ARTIGO MAGNETOMECâNICO COM UM ELEMENTO DE ORIENTAçãO DE BAIXA COERCITIVIDADE"<D>. Um material usado para formar um elemento de orientação (16) para um marcador de EAS magnetomecânico (10) tem uma coercitividade que é menor do que a coercitividade de elementos de orientação usados em marcadores magnetomecânicos convencionais. O marcador (10) formado com o material de baixa coercitividade pode ser desativado pela aplicação de um campo magnético CA em um nível inferior daquele requerido para desativação de mercadores convencionais (curva 26). O marcador (10) com o elemento de orientação (16) de baixa coercitividade pode ser desativado quando em uma distância maior de um dispositivo de desativação do que na prática anterior.
