Abstract: A semihard magnetic alloy for activation strips in magnetic antitheft systems contains 0.1 to 10% by weight Ni, 0.1 to 15% by weight Cr, 0.1 to 15% by weight Mo and Fe making up the rest with an overall proportion of Fe, Ni and Mo of less than 95% by weight of the alloy. The alloy is distinguished with respect to known alloys in use by its excellent magnetic properties and high resistance to corrosion. Furthermore, the alloy can be excellently cold shaped before tempering.

Abstract: For manufacturing a pulse generator wherein a voltage pulse dependent on the change in magnetic field can be achieved by sudden magnetic reversal (Barkhausen skip) given an applied magnetic field, an iron alloy is employed for one of the materials of the composite member, the additional alloy constituents of this iron alloy being selected such that a structural conversion with volume change respectively occurs at different temperatures. For producing the stressed condition, a thermal treatment is then implemented, which includes heating above the upper transition temperature and a cooling below the lower transition temperature. As a result, substantially greater stresses between the materials of the composite member arise, causing a pulse behavior significantly improved in comparison to known pulse generators of the type capable of recognizing constant or alternating magnetic fields.
