ABSTRACT:
Disclosed are a marker for a magnetic theft protection system, comprising:(a) at least one oblong alarm strip comprising an amorphous ferromagnetic alloy; and(b) at least one oblong activation strip comprising an alloy consisting essentially of formula NiaMobXcFeRest, wherein X is one or more of the elements from the group including Cr, W and V, and wherein a, b, and c are weight percentages, such that 15% by weight≦a≦25% by weight, 0% by weight≦b≦2.8% by weight, 0% by weight≦c≦8% by weight; and,wherein said activation strip has a coercitive force Hcof 10 A/cm to 25 A/cm and a remanence Brof at least 1.0 T; the activation strip itself, a tag containing the activation strip and/or marker, articles containing the marker or tag, methods for making the activation strip, and methods for making the marker.
