A magnetic theft detection system marker is adapted to generate magnetic fields at frequencies that (1) are harmonically related to an incident magnetic field applied within an interrogation zone and (2) habe selected tones that provide the marker with signal identity. The marker is an elongated, ductile strip of amorphous ferromagnetic material having a composition defined by the formula FeaCrbCcPdMoeCufBgSih where "a" ranges from about 63-81 atom % "b" ranges from about 0-10 atom %, "c" ranges from about 11-16 atom %, "d" ranges from about 4-10 atom %, "e" ranges from about 0-2 atom %, "f" ranges from about 0-1 atom %, "g" ranges from about 0-4 atom % and "i" ranges from about 0-2 atom %, with the proviso that them sum (c+d+g+h) ranges from 19-24 atom % and the fraction [c/(c+d+g+h)] is less than about 0.84.
