Abstract The possibility of a graphene-like Ising nanoparticle with high critical temperature or with a compensation point below its critical temperature is examined by decorating spin-3/2 atoms on the graphene-like Ising nanoparticle. The phase diagram and the temperature dependences of magnetization in the decorated nanoparticle are investigated by using the effective-field approximation with correlations. It is clarified how the paramagnetic graphene-like nanoparticle may change to a magnetic ordering nanoparticle by changing the physical parameters of decorated atom.

用自旋 3/2 原子装饰的类石墨烯伊辛纳米粒子中的补偿点现象

摘要 通过在类石墨烯 Ising 纳米粒子上装饰自旋 3/2 原子，研究了具有高临界温度或补偿点低于其临界温度的类石墨烯 Ising 纳米粒子的可能性。通过使用具有相关性的有效场近似，研究了装饰纳米颗粒中磁化强度的相图和温度依赖性。阐明了顺磁性类石墨烯纳米颗粒如何通过改变装饰原子的物理参数而转变为磁性有序纳米颗粒。
