Abstract

Patente de Invenção: <B>''MARCADOR COM GRANDE DESCONTINUIDADE BARKHAUSEN''<D>. Marcador EAS do tipo harmónico (120) que inclui um segmento de fio (123) formado de liga de cobalto. Para formar segmento de fio (123), a liga de acobalto é fundida (30) como um fio amorfo, estirado em molde (32) até um diâmetro menor, e depois recozido com aplicação de uma tensão longitudinal (34). O fio recozido é cortado (36) para produzir segmentos de fio que apresentam uma curva de histerese magnética com uma grande descontinuidade Barkhausen em nível limite inferior áquele que foi previamente alcançado.
