We introduce the stochastic Langevin–Gilbert equation and describe a simple numerical integration scheme for a pointwise solution converging to the Stratonovich interpretation. Reversal of the magnetisation vector is illustrated at various temperat

Damped gyromagnetic precession equations are discussed and solutions of a single-spin system are illustrated. A brief description of our variational finite element model of magnetisation dynamics is then given. The reversal of an isolated Voronoi gra

In this work we investigate the behavior of small arrays of interacting permalloy particles at the submicron level. Each individual particle is termed a nanoelement and is rectangular in form with varying elongation. The interest in such structures o

A micromagnetic model is used to investigate the dynamic behavior of a perpendicular recording medium which consists of a hard data layer and a soft underlayer. A variational finite element form of the Gilbert equation of motion is used to simulate t

Geometric integration refers to numerical methods which aim to preserve the qualitative and geometric features of a differential equation after discretization. In micromagnetics, the magnetization vector M represents a statistical average of magnetic

2-D regular nanoelements are of interest as micromagnetic model systems and in a number of sensor applications. In this paper we concentrate on a recent development in the form of experimental structures of arrays of small nanoelements which are 300

Investigation into the theoretical magnetic behaviour of permalloy is described. The material is discretised into a structure of nanoelements, so that we may employ micromagnetic simulations in order to investigate the material behaviour. In this pap

A two-dimensional micromagnetic simulation is developed using a spatial finite element method, with the dynamic Gilbert equations discretized by a Galerkin method. An algorithm is presented for the generation of granular microstructures via the Voron
