摘要

在蔡型准晶的近似晶体中观察到的各种磁序对于加深我们对准晶磁性的理解非常重要。我们利用具有团簇间相互作用的二十面体团簇模型，对之前通过经典蒙特卡洛模拟有效海森堡模型报告的钆基蔡型 1/1 近似晶体的磁序机制提供了直观的解释。

Revisiting the Magnetic Orders in Heisenberg Model for Tsai-Type Quasicrystal Approximant

The various magnetic orders observed in approximant crystals of a Tsai-type quasicrystal are important for deepening our understanding of magnetism in quasicrystals. Using an icosahedral cluster model with intercluster interactions, we provide an intuitive explanation of the mechanism of magnetic orders previously reported by classical Monte Carlo simulations of an effective Heisenberg model for Gd-based Tsai-type 1/1 approximant crystals.
