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…
Designing dislocation-driven polar vortex networks in twisted perovskites
William Sandholt, Nicolas Gauquelin, John Mangeri +21
Twisting two atomic layers produces a geometric moire pattern, but bonding-induced interfacial reconstruction fundamentally transforms this into an ordered dislocation network - a…
Instability-driven mechanically locked states in functional oxide membranes
Varun Harbola, Thomas Emil le Cozannet, Denis Alikin +10
Mechanical instabilities in thin solids offer a powerful route to engineer nonlinear responses, yet their controlled use in functional crystalline oxides has remained largely unexp…
