Study of the electronic structure properties in Co2NbIn/Sn Heusler alloys

Structural, electronic and magnetic properties of full-Heusler Co2NbIn and Co2NbSn compounds using density functional theory (DFT) have been studied. Lattice parameters obtained by volume optimization are 6.175A and 6179A for Co2NbIn and Co2NbSn respectively. Results suggest that Co2NbIn to be a half-metallic material with a gap of 0.58 eV at the Fermi level in the minority states while Co2NbSn has ferromagnetic behavior. The calculated magnetic moments are 2.00μB, 1.97μB for Co2NbIn and Co2NbSn. Formation energy and elastic parameters results suggest that both are energetically and elastically stable.Structural, electronic and magnetic properties of full-Heusler Co2NbIn and Co2NbSn compounds using density functional theory (DFT) have been studied.
