keV He离子轰击对交换偏置层系统影响的定量分析
Quantitative analysis of the influence of keV He ion bombardment on exchange bias layer systems
摘要：
离子轰击诱导的交换偏置层系统的磁图案化的机制，用于创建工程磁杂散场景观仍然不清楚。我们比较矢量磁光克尔效应测量的结果，最近提出的模型与时间相关的可旋转磁各向异性。结果表明，大规模减少的旋转磁各向异性相比，所有其他磁各向异性。我们反驳的假设，所有的磁各向异性比较削弱，并表明，离子轰击主要影响较小的反铁磁体颗粒。
英文摘要：
The mechanism of ion bombardment induced magnetic patterning of exchange bias layer systems for creating engineered magnetic stray field landscapes is still unclear. We compare results from vectorial magneto-optic Kerr effect measurements to a recently proposed model with time dependent rotatable magnetic anisotropy. Results show massive reduction of rotational magnetic anisotropy compared to all other magnetic anisotropies. We disprove the assumption of comparable weakening of all magnetic anisotropies and show that ion bombardment mainly influences smaller grains in the antiferromagnet.
