Thermoelectric power of magnetic metals

Single-crystalline study of the ferromagnetic kondo compound UCu0.9Sb2

“…This finding may indicate that the diffusion term is here dominating due to the presence of a peak of the density of states near the Fermi level, as is expected for a Kondo system. A large hump apparent in S ll (T) and a smaller one in S ⊥ (T), observed just below T C, may also be accounted for by the localized magnetic moment theory [14], in which inelastic scattering of electrons by phonons and localized spins are considered. A similar consideration exists for UPdSb, being a ferromagnet below T C = 77 K [15] …”

Comments on the thermoelectric power of the f-electron metallic compounds

“…Refs [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]) one can find the interpretations of TEP anomalies as caused by the isotropic s-f exchange scattering (in the one-band approach for the conduction electrons) and/or the electron-phonon scattering -considered in the Born approximation. These interpretations are based on the results of Refs [34][35][36] where the TEP maxima and the sign reversal were obtained within these oversimplified models.…”

“…The authors of Refs [34][35][36] performed the numerical calculations of the electron-phonon contribution to the thermoelectric power, S ph (T ), according to the formula derived within the variational method of solving the Boltzmann equation. [37][38][39] However, in their calculations they have not applied the scattering matrix elements presented in Refs [37][38][39], but other, received by themselves.…”

Influence of crystal field excitations on thermal and electrical resistivity of normal rare‐earth metals

“…In order to take into account the s–f interaction between of the spins of the conduction electrons and the total spin moments of 4f‐shells of RE ions, we treat this interaction by the method described in Refs. . The only difference is that the conduction electrons are assumed to gain or loose the energy of crystal field excitations of RE ion in the course of the scattering event, not the excitations of the magnetic moment below the Curie temperature in a crystal‐field‐free RE ferromagnet like in Ref.…”

“…The only difference is that the conduction electrons are assumed to gain or loose the energy of crystal field excitations of RE ion in the course of the scattering event, not the excitations of the magnetic moment below the Curie temperature in a crystal‐field‐free RE ferromagnet like in Ref. () or fictitious excitations of a two‐level system like in (). For simplicity, we also assume that the system is in paramagnetic state.…”
