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.

带有自旋1原子的石墨烯状Ising（spin-1 / 2）纳米颗粒中的磁性

摘要

通过有效场理论及其相关性，研究了用自旋1原子修饰的石墨烯状伊辛纳米粒子中的相图和磁化强度的热变化。讨论了spin-1原子的单离子各向异性对磁性的影响。当满足适当的条件时，可以澄清以下事实：纳米颗粒的转变温度可能变得大于块状蜂窝晶格的转变温度。装饰的纳米颗粒表现出在块状亚铁磁性材料中观察到的许多特征现象。
