“…According to phenomenological resonance model [4] the dominant contribution to S(T ) is caused by scat- tering between electrons of a broad s-band and a narrow f -band with the Lorentzian shape. There are two important parameters: the position of the f -electron band relative to the Fermi level, ε f − ε F and the width of the resonance peak Γ .…”

The magnetic and electronic properties including electrical resistivity, thermal conductivity and thermopower are discussed for the heavy fermion CeCu 4 Ag compound. The electrical resistivity shows a Kondo-like logarithmic increase up to a maximum at T = 75 K. Thermopower is positive over the whole temperature range and below T max = 25 K falls rapidly. The measured thermal conductivity of the CeCu 4 Ag compound increases with increasing temperature.

“…1, above 50 K, S a (T ) and S c (T ) may also be properly described within the so-called two-band approach that originates from the Hirst model [9]. In this simple theory it is assumed that the conduction electrons are scattered by a 4f -derived quasiparticle band of a Lorentzian form, located at F below the Fermi level.…”

Thermoelectric Power of Single-Crystalline Ce₂RhSi₃

High-quality single crystal of Ce 2 RhSi 3 was studied by means of thermoelectric power measurements carried out down to 2 K in external magnetic fields up to 13 T. The results obtained above 50 K were interpreted in terms of a modified two-band model that takes into account temperature variation of the width of 4f -derived narrow band located near the Fermi level. At lower temperatures the thermopower exhibits more complex temperature dependences that likely involve interplays of magnetic exchange, Kondo and crystal-field interactions.

“…To explain this observation, Gottwick et al [5] proposed a phenomenological model based on the two-band conductor model, which was originally proposed for 3D transition metals and alloys. The conduction electrons are assumed to be scattered by a 4f quasiparticle band of a Lorentzian form.…”

Thermoelectric Power of CeNi₄Si and YbNi₄Si Compounds

et al. 2008

The thermoelectric power was measured from 4.2 to 300 K for CeNi 4 Si and YbNi4Si. The thermoelectric power was analysed in the framework of the phenomenological resonance model. According to the model the dominant contribution to thermopower is caused by scattering between electrons of a broad s-band and a narrow f -band with the Lorentzian shape. The electron-hole analogy is reflected in the thermoelectric power behaviour of the investigated compounds.
