Specific Heat of YbNi4Si Compound
نویسنده
چکیده
The specific heat of YbNi4Si 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 θD = 320 K were derived. This small value shows that YbNi4Si cannot be classified as a heavy fermion system. These studies are completed by magnetic susceptibility, X-ray photoemission spectroscopy, and electrical resistivity.
