摘要
Within the framework of density functional theory, the electronic structure and magnetic properties have been studied for the Ti2FeSn full-Heusler compound. The ferromagnetic state is found to be energetically more favorable than paramagnetic and antiferromagnetic states. The spin-polarized results show that Ti2FeSn compound has half-metallic ferromagnetic character with a total spin moment of 2 mu(B) and a band gap in the minority spin channel of 0.489 eV, at the equilibrium lattice constant a = 6.342 angstrom.
