论文摘要
我们研究了具有dzyaloshinskii-moriya相互作用和平面内挫败感的二维各向异性抗铁磁旋转1/2海森贝格模型的磁性。 Tyablikov的随机相位及其解耦方案的框架内的自旋绿色函数的方法用于得出自旋波谱，sublattice磁化和过渡温度的表达式。基于这些表达式，我们对模型参数的不同值对其磁性的影响进行详细分析。该模型还适用于高-TC超导的母体化合物LA2CUO4，我们的结果与可用的实验数据相比。
We study the magnetic properties of the two-dimensional anisotropic antiferromagnetic spin-1/2 Heisenberg model with Dzyaloshinskii-Moriya interaction and in-plane frustration included. The method of spin Green functions within the framework of Tyablikov's random-phase-approximation decoupling scheme is used in order to derive expressions for the spin-wave spectrum, sublattice magnetization and transition temperature. Based on these expressions we perform a detailed analysis of the influence of varying values of model parameters on its magnetic properties. The model is also applied to the high-Tc superconducting parent compound La2Cuo4 and our results compared to available experimental data.
