DFT and spin model simulation data for Mn5Ge3 -- The folder experimental_cell contains simulations performed using the experimental crystal structure -- The folder distorted_cells contains simulations for the DFT-optimized crystal structure and for several distorted structures -- The folder model contains simulations for spin models with parameters fitted to experimental measurements The DFT simulations were performed with the codes Quantum Espresso (https://www.quantum-espresso.org) and JuKKR (https://jukkr.fz-juelich.de). Information about the respective code versions is printed inside the respective output files.
