ATHLETICS is a set of forward modelling software tools to enable electron holography and Lorentz microscopy images to be quickly and easily simulated from a known micromagnetic model. The first incarnation of the software is now available for downloading from our new ATHLETICS page of the NanoPaleoMag site. Written by James Bryson and Richard Harrison, the software is primarily designed to allow holography images to be created from the output files of a micromagnetic simulation (currently compatible with the LLG micromagnetic simulator). However it can also be used to generate holography images from any magnetic model – and is how we created the NANOPALEOMAGNETISM banner image for this site! More features are planned for the future, including the possibility to simulate MFM, scanning magnetic microscopy and X-ray microscopy images, so stay tuned for updates!
