Abstract
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.Keywords
