论文摘要

磁性纳米光刻的最新研究表明,各种复杂的磁状态与单个磁岛的纵横比的函数出现。我们提出了一个模型,该模型除了拟合实验外,还可以在特定纵横比预测具有连续对称性的磁性状态,并揭示了涡流和顶点状态之间的二元性。然后,我们的模型打开了工程新型人工旋转系统的新方法,以及它们在设备和计算中的复杂磁纹理中的应用。

Recent studies in magnetic nanolithography show that a variety of complex magnetic states emerge as a function of a single magnetic island's aspect ratio. We propose a model which, in addition to fitting experiments, predicts magnetic states with continuous symmetry at particular aspect ratios and reveals a duality between vortex and vertex states. Our model then opens new means of engineering novel types of artificial spin systems, and their application to complex magnetic textures in devices and computing.
