论文摘要
当“ Landau水平混合”是确定激发能的主要因素时，在固定填充因子NU = 2处的量子霍尔电子系统中的自旋叉式激发进行建模和研究。用于所讨论的纯电子激发的“单位式”方法使我们能够描述从非极化/paramgnet状态到偏光/非磁力磁铁的stoner转变。将理论结果与可用的实验数据进行了比较。
Spin-flip excitations in a quantum Hall electron system at fixed filling factor nu=2 are modelled and studied under conditions of a strong Coulomb interaction when the `Landau level mixing' is a dominant factor determining the excitation energy. The `one-exciton' approach used for the purely electronic excitations in question allows us to describe the Stoner transition from the unpolarized/paramgnet state to the polarized/ferromagnet one. The theoretical results are compared with the available experimental data.
