Influence of Field Annealing on Performance of Magneto-acoustic Markers
Amorphous Fe24 Co11.82 Ni47.3 Si1.47 B15 ribbons used for magnetomechanical electronic article surveillance system were prepared by rapid solidification. The ribbons were annealed at different conditions to improve their response performance. The influence of the annealing conditions on the ribbons performance has been investigated. The results show that the highest resonance amplitude in the ribbon was obtained for the specimen annealed at 340℃. It is favorable for improving acoustic magnetic properties of ribbons when the annealing magnetic field is perpendicular to the ribbons surface.
