The calculations are based on the full potential-linearized augmented plane wave (FPLAPW) method. The exchange and correlation potential is treated by the local density approximation (LDA) and generalized-gradient approximation (GGA), in addition the Engel–Vosko (EV-GGA) formalism was also applied. The DFT calculations show that these compounds have metallic origin. The contribution of different bands was analyzed from total and partial density of states curves. The values of the density of states at Fermi energy (N(EF)) for ThCu₅In (ThCu₅Sn) is 1.75 (1.63) states/eV unit cell. The bare electronic specific heat coefficient (γ) is found to be equal to 0.30 and 0.28 mJ/mol-K² for ThCu₅In and ThCu₅Sn, respectively. The Fermi surface of ThCu₅In/ThCu₅Sn is composed of three/four bands crossing along the R–Γ direction. The bonding features are analyzed by using the electronic charge density contour in the (101) crystallographic plane and it shows the covalent character of Cu–Cu and Sn/In–Cu bonds. The optical properties were also calculated and analyzed. 2014-03-14T08:12:35Z 2014-03-14T08:12:35Z 2014-02 Article Journal of Magnetism and Magnetic Materials, vol.352, 2014, pages 72–80 0304-8853 http://dspace.unimap.edu.my:80/dspace/handle/123456789/32755 http://www.sciencedirect.com/science/article/pii/S0304885313007300 http://dx.doi.org/10.1016/j.jmmm.2013.10.009 en Elsevier/NORTH-HOLLAND
