A new approach to (quasi) periodic boundary conditions in micromagnetics: the macrogeometry

By Hans Fangohr, Giuliano Bordignon, Matteo Franchin, Andreas Knittel, Peter A.J. de Groot and Thomas Fischbacher

Abstract

We present a new method to simulate repetitive ferromagnetic structures. This macro geometry approach combines treatment of short-range interactions (i.e. the exchange field) as for periodic boundary conditions with a specification of the arrangement of copies of the primary simulation cell n order to correctly include effects of the demagnetizing field. This method (i) solves a consistency problem that prevents the naive application of 3d periodic boundary conditions in micromagnetism and (ii) is well suited for the efficient simulation of repetitive systems of any size
