Abstract

We have performed first-principle calculations of the structural, electronic and magnetic properties of CoFeTiSb quaternary Heusler compound, using full-potential linearized augmented plane wave (FP-LAPW) scheme within the GGA. Features such as the lattice constant, the bulk modulus and its pressure derivative are reported. The electronic band structures and density of states of the CoFeTiSb quaternary compound show that the spin-up electrons are metallic, but the spin-down bands have a gap of 0.53 eV, resulting in stable half-metallic ferrimagnetic behavior with a magnetic moment of 2.00μ_B.
