The main origin of the perpendicular magnetic anisotropy in tbco amorphous films is the static interaction between the aspheric distribution charges of non - s tb ions and the aberrant crystal field produced in sputtering and deposition process . the magnetic dipole interaction is in a secondary cause 对于tbco非晶垂直磁化膜而言，具有非球对称电荷分布的非s态离子tb与溅射沉积薄膜过程中产生的畸变晶格场之间的静电相互作用构成了tbco非晶薄膜垂直磁各向异性的主要部分， tbco薄膜内的磁偶极相互作用构成了其次要部分。
