The atomic positions of Sm2NiMnO6 compound were optimized by minimizing the forces acting on the atoms, using the full potential linear augmented plane wave method. We employed the local density approximation (LDA), generalized gradient approximation (GGA) and Engel-Vosko GGA (EVGGA) to treat the exchange correlation potential by solving Kohn-Sham equations. The calculation shows that the compound is metallic with strong hybridization near the Fermi energy level (EF). The calculated density of states at the EF is about 21.60, 2452 and 2621 states'eV, and the bare linear low-temperature electronic specific heat coefficient (y) is found to be 3.74, 4.25 and 4.54 mJ/mol K2 for EVGGA, GGA and LDA, respectively. The Fermi surface is composed of two sheets. The bonding features of the compounds are analyzed using the electronic charge density in the (011) crystallographic plane. The dispersion of the optical constants was calculated and discussed. 2014-06-11T10:14:00Z 2014-06-11T10:14:00Z 2013-09 Article Journal of Magnetism and Magnetic Materials, vol. 342, 2013, pages 80-86 0304-8853 http://ezproxy.unimap.edu.my:2067/science/article/pii/S0304885313002904 http://dspace.unimap.edu.my:80/dspace/handle/123456789/35389 10.1016/j.jmmm.2013.04.060 en Elsevier BY.
