| 摘 要： | 介绍了声磁效应的发现与实验研究，确认了声磁效应是存在于铁磁材料表面的一种普遍物理现象．研究结果还表明：在退磁状态下产生声磁转换需要较强的声场强度，若在试样表面加上一直流偏置磁场，较小声强的声波也可以产生较高的声磁转换．此外，还对声磁转换的机理进行了简要地分析．

| Abstract: | The discovery and experiments on the acousto-magnetic effect are introduced, which confirmed that the acousto-magnetic effect is a universal physicalphenomenon of the ferromagnetic materials. For acousto-magnetic conversion under demagnethation state more intensive acoustic wave is required. When a D. C.bias magnetic field is applied on the surface of the sample, even a weak acousticwave can produce much stronger acousto-magnetic conversion. In addition, themechanism of the acousto-magnetic coversion is analyzed briefly. |
