ABSTRACT:
A magnetic theft detection system includes a glassy metal alloy strip having a value of magnetostriction near zero. The strip has been annealed to produce a step change in the magnetization versus applied field behavior (B-H loop) thereof, and has a composition consisting essentially of the formula.
