Research project: Computational Micromagnetics

Currently Active: 

Micromagnetics is a model for the behaviour of magnetisation at the nanoscale, and commonly used to support research in application areas ranging from biosensing and healthcare to fundamental materials development in academia and magnetic recording device development in industry.

Project Overview

Southampton has a long standing track record and active research programme in computational micromagnetics, including

  • Design and implementation of the Python-based Nmag finite-element simulation tool [1]
  • Contributions to the OOMMF simulation framework: higher order anisotropy extension modules [2] 
  • Supporting 3d visualisation of OOMMF simulation resuls through ovf2vtk [3] 
  • Development of the Macro Geometry (more flexible periodic boundary conditions in micromagnetics) [4 see publications tab]
  • Multi-physics micromagnetic simulations [5, 6]
  • Creation of 'benchmarks' to improve reliability of micromagnetic simulations [7, 8]

Development of new techniques is typically driven by requirements from project partners from academia and industry. Sample outputs include the study of a superconducting nano element coated with a ferromagnetic layer where the superconductivity can be switched on and off through an external magnetic field [9 see publications tab], domain wall motion in a nanowire with edge roughness [10 see publications tab], the simulation of experimental work on 3d pyramidal ferromagnetic shapes [11].
