摘要:

利用自洽谐波近似,研究了准二维易平面反铁磁模型在易平面内施加磁场时的相图。我们发现了一个线性依赖的转变温度作为一个功能的字段为大值的字段。我们的结果与自旋为1的蜂窝状化合物BaNi_2V_2O_3的实验数据一致

英文摘要:

The phase diagram of the quasi-two-dimensional easy-plane antiferromagnetic model, with a magnetic field applied in the easy plane, is studied using the self-consistent harmonic approximation. We found a linear dependence of the transition temperature as a function of the field for large values of the field. Our results are in agreement with experimental data for the spin-1 honeycomb compound BaNi_2V_2O_3
