Abstract

Una aleacion de metal vítreo que consiste esencialmente de la formula Fea Cob Nic Md Be Sif Cg, en donde M es por lo menos un miembro que se selecciona del grupo que consiste de molibeno, cromo y manganeso, "a-g" está en porcentaje atomico, "a" varía de aproximadamente 30 a aproximadamente 45, "b" varía de aproximadamente 4 a aproximadamente 40, "c" varía de aproximadamente 5 a aproximadamente 45, "d" varía de aproximadamente 0 a aproximadamente 3, "e" varía de aproximadamente 10 a aproximadamente 25, "f" varía de aproximadamente 0 a aproximadamente 15 g "g" varía de aproximadamente 0 a aproximadamente 2. La aleacion puede moldearse mediante solidificacion rápida en una cinta, se recuece para mejorar las propiedades magnéticas y se forma en un marcador que es especialmente apropiado para usarse en sistemas de supervision de artículos accionados magneto mecánicamente. Ventajosamente, el marcador está caracterizado por una repuesta de magnetizacion relativamente lineal dentro del régimen de frecuencia en donde los sistemas del marcador armonico funcionan magnéticamente. Las amplitudes de voltaje detectadas para el marcador son elevadas, y la interferencia entre los sistemas de supervision basándose en la resonancia mecánica y la re-radiancia armonica virtualmente se elimina.
