A magnetostrictive element for use in a magnetomechanical electronic article surveillance marker is formed by annealing a continuous ribbon of an amorphous metal alloy. The alloy ribbon is transported from reel to reel through an oven in which a transverse saturating magnetic field is applied to the ribbon. The annealed ribbon is cut into discrete strips which are suitable for use as magnetostrictive elements.
