应变和厚度对CoFe(011)薄膜磁晶各向异性的影响

Strain and thickness effects on magnetocrystalline anisotropy of CoFe(011) films

Eunsung Jekal, Phuong Dao

摘要:

研究了CoFe(011)薄膜的MCA随应变强度和薄膜厚度的变化。结果表明,垂直磁晶各向异性(MCA)能(EMCA)随xy面晶格常数的压缩而增强,而面内MCA因xy面的拉伸应变而成为易轴。电子结构特征可以解释EMCA行为的原因。

英文摘要:

We investigate MCA of CoFe(011) thin films as a function of strength of strain and film thickness has been studied. It is elucidated that perpendicular magnetocystalline anisotropy (MCA) energy (EMCA) is getting stronger with compressed xy-plane lattice constant while in-plane MCA is become an easy-axis by tensile strain on xy-plane. The reason of the EMCA behaviors can be explained by features of electronic structures.
