ATHLETICS: a simple and quick way to simulate Lorentz contrast, electron holography and stray field images.
ATHLETICS (A Tremendous Holography and LorEnTz Image Creation Simulator) is a free software package that can create Lorentz contrast, electron holography and stray out-of-plane magnetic field images of the outputs from micromagnetic simulations. This allows for qualitative and quantitative comparisons of micromagnetic calulations to various experimental results, often allowing for an understanding of the experimental image features. The software is written using Igor Pro by Wavemetrics. Although Igor Pro is a commercial package, Wavemetrics offer a fully functional demo version for both Mac and Windows, so you can download it and get started right away!
The package is designed to work best on output data from LLG micromagnetic simulations, saved either as .llg_dom files or as .txt files. However any confiuration of magnetic moments is a possible starting point, and feel free to contact the authors and we will be happy to help modify the script to any starting input.
ATHLETICS is written by James Bryson and Richard Harrison of the Department of Earth Sciences, University of Cambridge. Please feel free to contact the authors with any questions/bug reports/feature requests.
ATHLETICS can be used for free, but please cite the following reference in any scientific publications that use ATHLETICS outputs:
