Abstract

1,266,787. Magnetic materials. WESTERN ELECTRIC CO. Inc. 27 March, 1969 [1 April, 1968 (2)], No. 15998/69. Heading H1H. [Also in Division C7] A magnetic material has the general formula (C)x(RE) where C consists of A and B, A being Co and/or Fe and B being Cu, Ni and/or Al; RE is Sin, Ce, Gd, Pr, La, Y, Nd and/or Ho; and x has a value of 5 to 8À5; the composition being within the area z or the ternary diagram bounded by lines drawn between the points: Up to 10% of the material may be replaced by Ca, Sr, Ba and/or V. The material may be made by melting the components and then cooling rapidly. Cooling over the range of 1600-600‹ C. is preferably carried out for a maximum time of 15 minutes. The material may be annealed at 300-700‹ C. and pulverized, the resulting powder being orientated in a magnetic field and then sintered. The following materials are specified: Co 3 Cu 2 Sm, Co 4 Cu 1À5 Sm, Co 5À07 Cu 1À17 - Sm, Co 4 Cu 1À5 Ce and Co 5À25 Cu 1À5 Ce.
