OOMMF Tutorial Series

This page provides background references and resources for the Micromagnetics and OOMMF online tutorial series that ran from 21-May-2020 through 9-June-2020. There were four sessions, with each session lasting approximately two hours.

Background reading

The following papers provide nice introductions to micromagnetics theory and practice:

• Micromagnetism by Lukas Exl, Dieter Suess and Thomas Schrefl.
• General Micromagnetic Theory and Applications, Helmut Kronmüller in Materials Science and Technology, 2019 Wiley-VCH Verlag GmbH & Co. KGaA. DOI: 10.1002/9783527603978.mst0460
• Numerical micromagnetics: Finite difference methods, J. Miltat and M.J. Donahue, in Handbook of magnetism and advanced magnetic materials, edited by H. Kronmüller and S. Parkin (Wiley-Interscience, Chichester), Vol. 2, pp. 742-764 (Sep 2007). DOI: 10.1002/9780470022184.hmm202    (Manuscript)

OOMMF Installation

The OOMMF User's Guide includes detailed instructions on installing OOMMF, or you can look at the OOMMF Installation Overview. An easy option for beginners is to bypass installing OOMMF altogether and run OOMMF through a web-interface with a free account at nanoHUB. There is a nanoHUB OOMMF First Time User's Guide to help getting started.
