Exact demagnetisation field for periodic one-dimensional array of rectangular prisms
Frederik Laust Durhuus, Andrea Roberto Insinga, Rasmus Bjørk
The magnetic field from a uniformly magnetised, rectangular prism is known exactly, which is the basis for a large number of micromagnetic simulations. Here we derive an analytical…

Including sample shape in micromagnetics with 3D periodic boundary conditions
Frederik Laust Durhuus, Andrea Roberto Insinga, Rasmus Bjørk
Periodic boundary conditions (PBCs) for computing magnetic fields in repeating magnetic structures, e.g. in micromagnetic simulations, are typically imposed using the quasi periodi…
