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 對于tbco非晶垂直磁化膜而言,具有非球?qū)ΨQ電荷分布的非s態(tài)離子tb與濺射沉積薄膜過程中產(chǎn)生的畸變晶格場之間的靜電相互作用構(gòu)成了tbco非晶薄膜垂直磁各向異性的主要部分, tbco薄膜內(nèi)的磁偶極相互作用構(gòu)成了其次要部分。
