Abstracts
The specific heat of YbNi_4Si has been analyzed considering the electronic contribution and the lattice contributions in frames of the Debye model. Based on the specific heat measurements, the electronic specific heat coefficient γ = 25 mJ mol^{-1} K^{-2} and the Debye temperature θ_D = 320 K were derived. This small value shows that YbNi_4Si cannot be classified as a heavy fermion system. These studies are completed by magnetic susceptibility, X-ray photoemission spectroscopy, and electrical resistivity.
