41593CAN1A Abstract of the Disclosure A magnetic marker for use with electronic article surveillance (EAS) systems in which a two-directional very high order harmonic response is obtained. The markers comprise two pairs of elongated strips of low coercive force, high permeability material positioned in a tic-tac-toe configuration such that the strips at right angles to an applied field of an EAS system collect and concentrate the lines of flux associated with the field into the strips parallel to the field, the concentrated flux being sufficient to result in a high harmonic response.
