Abstract

Una aleacion de metal vítreo que consiste esencialmente de la formula COa Feb Nic Md Be Sif Cg, en donde M se selecciona del molibdeno y cromo y "a", "b", "c", "d", "f", "g" son el porcentaje atomico, "a" varía de aproximadamente 40 a aproxiamdamente 43, "b" varía de aproximadamente 35 a aproximadamente 42 y "c" varía de aproximadamente 0 a aproximadamente 5, "d" varía de aproxiamdamente 0 a aproximadamente 3, "e" varía de aproximadamente 10 a aproximadamente 25, "f" varía de aproximadamente 0 a aproximadamente 2. La aleacion puede molerse moldearse mediante solidificacion rápida en una cienta, recorcerse para mejorar las propiedades magnéticas de la misma, y formarse en un marcador que está especialmente apropiado para usarse en sistemas de supervision de artículos accionados mecánicamente. Ventajosamente, el marcador está caracterizado por una respuesta de magenetizacion relativamente lineal en el régimen de frecuencia en donde funcionan magnéticamente los sistemas del marcador armonico. 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 se elimina virtualmente.
