The magnetic order of domain walls (DWs) based on zigzag graphene nanoribbons (ZGNR) with mixed spins S = 3/2 and σ = 1 is investigated using the Monte Carlo study under effect size. Phase diagrams of DWs based ZGNR were found. Magnetic phases more stable are found in several planes. The thermal of total magnetizations, partial, and magnetic susceptibilities is found. The reduced Néel temperature is deduced. The effect of exchange interaction and crystal field on total magnetizations is studied. The magnetic hysteresis cycles of DWs based ZGNR with mixed spins S = 3/2 and σ = 1 under effect of size, temperature, exchange interaction and crystal field are found.

锯齿形石墨烯纳米带作用下畴壁的磁序研究

使用蒙特卡洛研究在效应量下研究了基于曲折形石墨烯纳米带(ZGNR)且混合自旋S = 3/2和σ= 1的畴壁(DW)的磁阶。找到了基于DW的ZGNR的相图。在多个平面中发现了更稳定的磁相。发现总磁化,部分磁化率和磁化率的热。推断出降低的尼尔温度。研究了交换相互作用和晶体场对总磁化强度的影响。发现在尺寸,温度,交换相互作用和晶体场的影响下,具有混合自旋S = 3/2和σ= 1的基于DWs的ZGNR的磁滞循环。
