Abstract

We study magnetism in the 2D magnets with a \(d\)-metal sub-lattice based on the density functional theory and Monte-Carlo simulations. The phenomena of ligand field and the macroscopic nature of \(p{\text{-}}d\) orbitals hybridization has been discussed widely. For a magnetism in the 2D materials with a honeycomb and hexagonal \(d\)-metal sub-latices we derive an effective Hamiltonian for a spin subsystem with and without inclusion next nearest-neighbors interaction and higher-order terms. Based on the proposed models critical temperature \({{T}_{{\text{C}}}}\) for a wide range of compounds estimated.

类海森堡模型框架下的金属二钙化物磁性：DFT 和蒙特卡洛方法

摘要基于密度泛函理论和蒙特卡罗模拟，研究了含有\(d\) -金属亚晶格的二维磁体的磁性。配体场现象和\(p{\text{-}}d\)轨道杂化的宏观性质得到了广泛的讨论。对于具有蜂窝和六角形\(d\) -金属亚晶格的二维材料中的磁性，我们推导了包含和不包含次近邻相互作用和高阶项的自旋子系统的有效哈密顿量。基于所提出的模型，对大范围化合物的临界温度\({{T}_{{\text{C}}}}\)进行估计。
