Disclosed are markers for a magnetic theft protection system, which markers contain at least one oblong alarm strip made of an amorphous ferromagnetic alloy and at least one activation strip made of a molybdenum-free semi-hard magnetic alloy consisting essentially of Ni<SUB>a</SUB>M<SUB>b</SUB>Fe<SUB>Rest</SUB>, wherein M is one or more of the elements from the group including Cr, W and V, and wherein a and b are weight percentages such that 15% by weight<=a<=25% by weight, and 2% by weight<=b<=8% by weight. The activation strip has a coercive force H<SUB>c </SUB>of 10 A/cm to 25 A/cm and a remanence B<SUB>r </SUB>of at least 0.9 T
