Magnon scatterings affect the performance of magnonic devices directly, and dynamic dipolar field (DDF) is crucial in the scattering potential. In this paper, a theoretical model of the DDF in low-dimensional magnetic systems is present, and simulations give the summation area to achieve good accuracy in the DDF calculation, though the dipolar field is a long-range interaction. Calculation in a finite-size thin film indicates that due to the breaking of translational symmetry, the DDF increases evidently in the borders and the corners. The DDF near the vertex of the thin film is several orders magnitude higher than that in the inside area, making the corners prominent in the magnon scatterings.

Ice Model

In the discrete 2D XY model of finite number of point dipoles of square spin ice, the order parameter has been calculated exactly as the average size of the maximal cluster. The finite size and edge effects do not allow research the critical behavior of the phase transition for finite systems. It is found that frustrations in spin ice model with long-range interaction are possible only in presence of symmetry for the distribution of magnetic moments.
