采用熔融快速淬火制备了电子商品监视系统用的Fe24Co11.82Ni47.3Si1.47B15非晶条带,经不同条件退火处理以提高其响应性能,研究了退火条件对条带用于磁机械电子监视系统时声磁性能的影响.结果表明退火温度在340℃时具有最大共振幅值,退火磁场垂直于条带面有利于增强条带的声磁性能.
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.
