Abstract The decorated nanoparticle which is consisted of two paramagnetic (hexagonal and trimer) nanoparticles and tied by an exchange interaction is examined by the effective-field theory with correlations. It is discussed whether it can exhibit a critical temperature larger than that of a bulk system. The phase diagram and the thermal variations of magnetizations are investigated. When some appropriate conditions are satisfied for exchange interactions, a compensation point and characteristic thermal variations can be found in the total magnetization.

用 Ising 三聚体装饰的类石墨烯 Ising 纳米粒子：高临界温度、补偿点和特征磁化曲线

摘要 由两个顺磁性（六边形和三聚体）纳米颗粒组成并通过交换相互作用连接的装饰纳米颗粒通过具有相关性的有效场理论进行了研究。讨论了它是否可以表现出比体系统更大的临界温度。研究了相图和磁化强度的热变化。当满足交换相互作用的一些适当条件时，可以在总磁化强度中找到补偿点和特征热变化。
