论文摘要
当所有电子均处于地面坐标状态时，在低温下考虑二维Wigner簇的自旋状态。自旋子系统行为由抗磁性交换积分确定。在存在磁场的情况下，在ISING模型中描述了这种系统中的自旋状态。通过计算机模拟可以找到群集的自旋结构，相关函数和磁敏感性。结果表明，由于磁诱导的自旋子系统重排，自旋敏感性相对于磁场经历了振荡。
Spin states of two-dimensional Wigner clusters are considered at low temperatures, when all electrons are in ground coordinate states. The spin subsystem behavior is determined by antiferromagnetic exchange integrals. The spin states in such a system in the presence of a magnetic field are described in terms of the Ising model. The spin structure, correlation function, and magnetic susceptibility of the cluster are found by computer simulations. It is shown that the spin susceptibility experiences oscillations with respect to the magnetic field, owing to the magnetoinduced spin subsystem rearrangements.
