Data for "Probing stress and magnetism at high pressures with two-dimensional quantum sensors"

Diffraction pattern → Contains TEM diffraction images (.tif) and Gatan original files (.dm4) corresponding to Supplementary Fig. 1. DFT calculation → Contains input files (POSCAR, INCAR, KPOINTS, POTCAR) used to compute ferromagnetic (FM) and antiferromagnetic (AFM) configurations in a 2×2 supercell. The resulting energy differences were used to calculate the exchange constant J, and calculations were extended under pressures up to 2 GPa (Supplementary Fig. 3).
