Abstract Fe thin films were deposited on commercial CD substrates using the magnetron sputtering technique, to examine the effect of the patterned underlayer on their structural and magnetic properties. We report that the coercive field and magnetic anisotropy of these iron grained thin films are strongly depended on the patterned substrate, in accordance with Monte Carlo simulations performed using the Metropolis algorithm. The model developed well explains the role of the exchange and dipole-dipole interparticle magnetic interactions between the Fe grains, and predicts the optimum conditions for advanced magnetic sensor applications.

商用 CD 基板上的垂直磁各向异性机制

摘要 Fe 薄膜使用磁控溅射技术沉积在商用 CD 基板上，以检查图案化底层对其结构和磁性能的影响。我们报告说，根据使用 Metropolis 算法执行的蒙特卡罗模拟，这些铁晶粒薄膜的矫顽场和磁各向异性在很大程度上取决于图案化基板。开发的模型很好地解释了 Fe 晶粒之间的交换和偶极-偶极粒子间磁相互作用的作用，并预测了高级磁传感器应用的最佳条件。
