我们提出了磁性纳米结构阵列的磁性和磁化反转过程的系统研究。我们在磁环中观察到，不同平衡态之间的转变强烈依赖于静磁相互作用。对于磁性纳米线，观察到当线的厚度在固定的横向尺寸上变化时，从相干旋转到反转卷曲模式的转变。我们发现，在反点纳米结构中，磁性各向异性可以通过设计晶格几何来控制。
We present a systematic investigation of the magnetic properties and magnetization reversal processes in arrays of magnetic nanostructures. We observed in magnetic rings that the transitions between different equilibrium states are strongly dependent on magnetostatic interactions. For magnetic nanowires, a transition from coherent rotation to curling mode of reversal as the thickness of the wire is varied for fixed lateral dimensions was observed. We found in anti-dot nanostructures that the magnetic anisotropy can be controlled by engineering the lattice geometry.
