a, Classification of magnetic materials based on the condition of symmetry-enforced M = 0 within the spin-space point group Pspin (or SSG) and MSG. The quantities and proportions of each type of materials in the MAGNDATA database are presented, including DFT-assisted identification. b, Left, crystal structure and magnetic configuration of Mn3Sn. Right, the spin and orbital magnetizations of Mn3Sn as a function of SOC strength obtained from DFT calculations. The horizontal axis represents the ratio of the SOC coefficient used in the calculation (λ) to the actual SOC value for Mn3Sn (λ0).
