Abstract In this work, we study the dielectric properties of a mixed spins (S = 5/2 and σ = 2) and (σ = 5/2 and S = 2) with Blume Capel model in a nanotube structure via Monte Carlo simulations for a several sizes. We start by discussing the ground state phase diagrams corresponding to several physical parameters. Then the polarizations have been analyzed. Besides, we explore the polarization behavior under the effect of the exchange coupling interaction and the crystal anisotropy fields. Furthermore, we investigate the presence of the compensation and critical temperatures resulted from the variation of the coefficient coupling and the crystal anisotropy field. Finally, the variation of the total polarizations as a function of the exchange coupling interaction, the crystal anisotropy field and the temperature have been discussed.

纳米管系统中混合自旋 (S=5/2, σ=2) 和 (σ= 5/2, S=2) 的介电特性：蒙特卡罗研究

摘要 在这项工作中，我们通过蒙特卡罗模拟在纳米管结构中使用 Blume Capel 模型研究了混合自旋（S = 5/2 和 σ = 2）和（σ = 5/2 和 S = 2）的介电特性。几个尺寸。我们首先讨论对应于几个物理参数的基态相图。然后对极化进行了分析。此外，我们探索了在交换耦合相互作用和晶体各向异性场作用下的极化行为。此外，我们研究了由系数耦合和晶体各向异性场的变化引起的补偿和临界温度的存在。最后，讨论了作为交换耦合相互作用、晶体各向异性场和温度的函数的总极化的变化。
