本文计算了典型圆柱形点阵的静磁耦合能。考虑了亚微米尺寸的点的正方形晶格和纳米尺寸的点的矩形“人字形”晶格。方点阵的基态是连续简并的非共线反铁磁。对于人字形点阵，计算了静磁耦合引起的单轴各向异性。讨论了亚微米和纳米尺度Co点的一些实验结果。(C)1999年美国物理学会。[S0003-6951（99）03029-6]。
In this letter the calculations of the magnetostatic coupling energy are done for the typical cylindrical dot arrays. The square lattice of submicron-size dots and rectangular "herringbone" lattice of nanoscaled dots are considered. The ground state of the square dot lattice is shown to be continuously degenerated noncollinear antiferromagnetic. For the herringbone dot lattice the uniaxial anisotropy induced by magnetostatic coupling is calculated. Some experimental results on the submicron dots and nanometer scaled Co dots are discussed.
