Magnetostatic waves via PS-LL

Our work to numerically solve for magnetostatic waves within the pseudospectral Landau-Lifshitz (PS-LL) model was just published in npj Computational Materials.

While the PS-LL model was initially developed to resolve the transition from atomic to continuum dynamics, its general formulation allows for the use of any kernel. Here, we use a magnetodipolar kernel that can represent in-plane magnetostatic waves, both backward volume and surface. We demonstrate that the use of this kernel can speed up simulations by a factor of two at the expense of losing the particularities of the magnetization distribution at physical edges.
