Abstract
The magnetic properties of a thin strip of amorphous alloy are improved by imparting external stress such as tensile force and compressive force as by means of rollers to the surfaces of the thin strip of alloy while keeping the thin strip heated at a temperature which does not impair the mechanical properties of the amorphous alloy, thereby eliminating the internal stress of the alloy which tends to impair the magnetic properties.
