From TEM bright field image, it can be seen that the surface image of CoPt formed discrete islands, and gradually change to continuous film as the CoPt thickness increase. After annealed at 700℃ for 30 minutes, the single domain state is found by the observation of MFM images at 7.5 nm CoPt. At single domain state, the variation of coercivity with particle size agree with the theory of single domain particles.

由TEM平面明视野影像可以看到，随著CoPt厚度的增加，其表面型态由不连续岛状结构逐渐转变为连续膜，从MFM图可以发现於700℃退火30分钟之CoPt(7.5 nm)为单磁区状态，在此单磁区状态其矫顽磁力随颗粒直径的变化符合单磁区理论。
