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…
Scalable physical source-to-field inference with hypernetworks
Berian James, Stefan Pollok, Ignacio Peis +3
We present a generative model that amortises computation for the field and potential around e.g.~gravitational or electromagnetic sources. Exact numerical calculation has either co…
The magnetic scalar potential and demagnetization vector for a cylinder tile
Rasmus Bjørk
A closed-form solution for the magnetic scalar potential generated by a uniformly magnetized cylindrical slice and a full cylinder is determined by solving Poisson's equation analy…
