ABSTRACT:
A nickel based amorphous alloy in elongated ribbon form is subjected to a stress in the range of 20 to 40 kilograms per square millimeter, and is heated to temperatures below the melting point, preferably in the range of 200.degree. C. Such heating under stress is maintained for a period of time, whereupon the material is cooled. There results a residual enhancement of the magnetic properties which occur by application of stress, but which are extinguished when the stress is removed.
