Electronic structure of Fe2CrSn

From the first principles calculation based on the density functional theory, we find that consideration of electron–electron correlation drives Fe₂CrSn from a barely half-metallic state to a magnetic semiconductor. However, in both cases, the magnetic state remains ferrimagnetic with a total spin moment of 2μ_B$2{\mathrm{\mu }}_{\mathrm{B}}$, with Cr carrying a large local moment that is oppositely aligned to that of Fe.
