摘要

磁纳米点的涡旋态由于其面内杂散场的减小而在数据存储中具有很高的技术价值。数据可以存储在磁芯极性和/或涡旋手性中。虽然磁性纳米点的磁化反转是通过涡旋状态发生的，但定义和切换磁芯极性和/或涡旋手性就不那么简单了。对于单个纳米粒子，先前的研究发现，可以使用倾斜的场脉冲来切换这些值。本文研究了恒定倾斜场和开关外磁场对小纳米点团簇的影响。

Influence of Tilted Fields on Magnetization Reversal in Fe Nanodots

Vortex states in magnetic nanodots are of high technological interest for data storage applications due to the reduced in-plane stray fields. Data can be stored in the core polarity and/or the vortex chirality. While magnetization reversal in magnetic nanodots occurs via vortex states for a broad range of dimensions, defining and switching core polarity and/or the vortex chirality is less simple. For single nanoparticles, previous studies found that a tilted field pulse can be used to switch these values. Here, the influence of a constant tilted field in addition to the switched external magnetic field on a small nanodot cluster is investigated.
