ABSTRACT The phase diagram and the thermal variations of magnetizations in a graphene-like Ising nanoparticle decorated with spin-1 atom are examined by the effective-field theory with correlations. The effects of single-ion anisotropy of spin-1 atom to the magnetic properties are discussed. The following facts are clarified, when the appropriate conditions are satisfied: The transition temperature of the nanoparticle may become larger than that of bulk honeycomb lattice. The decorated nanoparticle exhibits many characteristic phenomena observed in bulk ferrimagnetic materials.

用自旋1原子装饰的类石墨烯伊辛（自旋1/2）纳米粒子的磁性

摘要 通过具有相关性的有效场理论，研究了用自旋 1 原子装饰的类石墨烯伊辛纳米粒子中的相图和磁化强度的热变化。讨论了自旋1原子的单离子各向异性对磁性能的影响。当满足适当的条件时，以下事实得到澄清： 纳米颗粒的转变温度可能变得比块状蜂窝晶格的转变温度大。装饰的纳米颗粒表现出在块状亚铁磁材料中观察到的许多特征现象。
