Özet

Density functional calculations performed on the Ti2CoAl Heusler compound confirm it to be a half-metallic ferrimagnet with the spin-down energy gap of 0.49 eV. The Ti2CoAl Heusler compound has a magnetic moment of 2 μB at the equilibrium lattice constant a=6.14 Å. The Ti2CoAl Heusler compound is ferrimagnetic and maintains the half-metallic character having 100% polarization for lattice constants ranging between 5.85 and 6.44 Å. © 2011 Elsevier B.V.
