摘要

详细了解磁性纳米结构中的磁化反转和可能的磁性结构对于高密度磁记忆至关重要。纳米结构磁体的磁性与铁磁畴大小相当或更小,为新物理学提供了巨大的潜力。我们提出了一项系统研究亚100纳米纳米点的磁反转的结果,以及这种反转如何受到各种各向异性、温度和交换偏置的影响。

Effect of Anisotropy and Exchange Bias on Reversal of Sub-100 nm Magnetic Dots
Detailed knowledge of magnetization reversal and possible magnetic configurations in magnetic nanostructures is essential for high-density magnetic memory. Magnetism of nanostructured magnets, of size comparable to or smaller than ferromagnetic domain size, offers a great potential for new physics. We present results of a systematic study of magnetic reversal in sub-100 nm nanodots, and how this reversal can be affected by various types of anisotropy, temperature, and exchange bias.
