AI 中文摘要
人工自旋冰（ASI）是将单畴纳米磁体装饰在几何晶格上的结构，可用于研究易变晶格几何上的磁相互作用。我们将ASI的研究扩展至单菱形铺砌，以非周期性六边形$H_{\ rac{1}{2}\ rac{1}{2}}$铺砌为基础结构模拟ASI，并以周期性骰子晶格做额外对比。采用点偶极子 metropolis 蒙特卡洛方法冷却纳米岛阵列形成低能构型，通过互补微磁模拟识别单个顶点激发，结合最终自旋态的能量与电荷分布，提出非周期性系统的潜在基态自旋构型。
英文摘要
Artificial spin ices (ASIs) are decorations of single domain nanomagnets on geometric lattices allowing for study of magnetic interactions on easily varied lattice geometries. We extend the study of ASIs on single rhomb tilings by simulating an ASI with the aperiodic hexagonal $H_{\frac{1}{2}\frac{1}{2}}$ tiling as the base structure, and the periodic dice lattice for additional comparison. Using a point dipole metropolis Monte Carlo approach, we cool our arrays of nanoislands to form a low energy configuration, assessing individual vertex excitations as identified through complementary micromagnetic simulations. Using the energy and charge landscape of final spin states, we propose a potential ground state spin configuration for the aperiodic system.
