人工戈薇旋冰中冰规则的直接观测

Direct observation of the ice rule in artificial kagome spin ice

Yi Qi, T. Brintlinger, John Cumings

摘要:

最近,人们对模拟几何阻挫材料行为的制造系统产生了极大的兴趣。我们提出了这样一个人工自旋冰系统的二维kagome晶格上的充分实现,并证明了严格遵守当地冰规则,直接计算个人的伪自旋。由此产生的自旋配置不仅显示本地冰规则和长程无序,而且相关性与自旋冰蒙特卡罗计算一致。我们的研究结果表明,偶极校正是显着的,在这个系统中,在烧绿石自旋冰,他们打开了一扇门,进一步研究挫折一般。

英文摘要:

Recently, significant interest has emerged in fabricated systems that mimic the behavior of geometrically-frustrated materials. We present the full realization of such an artificial spin ice system on a two-dimensional kagome lattice and demonstrate rigid adherence to the local ice rule by directly counting individual pseudo-spins. The resulting spin configurations show not only local ice rules and long-range disorder, but also correlations consistent with spin ice Monte Carlo calculations. Our results suggest that dipolar corrections are significant in this system, as in pyrochlore spin ice, and they open a door to further studies of frustration in general.
