Magnetic and structural properties of Co2MnSi based Heusler compound

The influence of antisite disorder occupancies on the magnetic properties of the half-metallic Co2MnSi compound was studied by experimental techniques and first-principles calculations. The neutron diffraction studies show almost equal amount of Mn and Co disorders of 6.5% and 7.6%, which was found to be in good agreement with density functional theory (DFT) calculations of the stable Co2MnSi system with the corresponding disorders. DFT studies …
