| The studies of the electronic structure and the specific heat of YNi4Si are reported. Below the Fermi energy (EF) the density of states contains mainly the 3d states of Ni, which hybridized with 4d states of Y and 3p states of Si. The theoretical electronic specific heat coefficient (12.32 mJ/(mol K2)) obtained for equilibrium lattice parameters and the experimental value (13 mJ/(mol K2)) are in a reasonable agreement. |
