ABSTRACT:
An amorphous alloy free of magnetostriction is employed in anti-theft labels, magnetic field detectors or the like, having a saturation induction of B.sub.s .ltoreq.0.5T and a good responsiveness given an annealing treatment in the magnetic field for achieving a remanance relationship of B.sub.r /B.sub.s >0.6.
