Abstract
A nickel based amorphous alloy in elongated ribbon form is passed between two rollers to obtain approximately a one third reduction in thickness. The rolled alloy samples may then be subjected to elastic tensile loading, which tends to increase remanence and decrease coercivity. The rolling process tends to reduce the unloaded remanence and thereby to improve the load versus remanence range sensitivity by a considerable amount.
