本文讨论了非晶C或Ti 90 Cr 10底层的Co 73 Cr 18 Pt 6Ta 3垂直磁记录介质中晶粒取向与色散、极性和氢键三种表面能分量的关系。通过测量测试液体在薄膜上的接触角，由扩展的Fowkes理论计算薄膜的每个表面能分量。实验结果表明，C底层Co73Cr18Pt6Ta3磁化膜表面能的极性分量对Co73Cr18Pt6Ta3磁化膜的Co [001]择优取向影响较大，而Ti 90Cr10底层Co73Cr18Pt6Ta3磁性层表面能对Co [001]择优取向分布影响较小。
The relationship between crystallographic grain orientation and the three kinds of surface energy components; dispersion, polar, and hydrogen bonding components, in Co73Cr18Pt6Ta3perpendicular magnetic recording media with an amorphous C or a Ti90Cr10underlayer was discussed. Each surface energy component of the thin film was calculated from an extended Fowkes theory by measuring the contact angle of a test liquid on the thin film. The experimental results revealed that the polar component of surface energy of the Co73Cr18Pt6Ta3magnetization film with the C underlayer affected greatly the Co [001] preferred orientation of the Co73Cr18Pt6Ta3magnetization film, while the surface energy of the Co73Cr18Pt6Ta3magnetic layer with the Ti90Cr10underlayer had little influence on the distribution of it.
