The provided AiiDA database contains magnetic electronic structure calculations from a selection of full (L2₁) and inverse (XA) Heusler alloys. The examined crystal structures were taken from the Materials Project database. The data was obtained to examine the spin-polarization of the density of states amongst different compounds. The FLAPW code FLEUR has been combined with the GGA-based PBE functional to compute the structures. Spin-orbit interaction has been considered in second variation within the presented calculations.
