基于唯象微磁理论和磁弛豫处理，讨论了多层膜(Co/Pt)和(Co/Pd)的矫顽力机制。根据微磁理论，发现(Co/Pt)和(Co/Pd)薄膜的钉扎尺寸都是几个数量级的/spl Aring/，而非晶态TbFeCo薄膜的钉扎尺寸约为100/spl Aring/。另一方面，磁弛豫法估计这些多层膜的巴克豪森体积约为10/sup-18/cm/sup 3/。
The coercivity mechanism of multilayer (Co/Pt) and (Co/Pd) is discussed based on the phenomenological micromagnetic theory and the magnetic relaxation treatment. Based on the micromagnetic theory, the pinning size of the order of a few /spl Aring/ is found for both (Co/Pt) and (Co/Pd), but about 100 /spl Aring/ for an amorphous TbFeCo film. On the other hand, the magnetic relaxation approach estimates the Barkhausen volume of the order of 10/sup -18/cm/sup 3/ for these multilayers.
