概要
- 論文の詳細を見る
The electrical and thermal resistivities due to the spin fluctuations in weakly and nearly ferromagnetic metals are studied by using the s-d band model and the self-consistently renormalized spin fluctuation theory for the d-band electrons. The resistivities are calculated in the whole temperature range of interest and their temperature dependences are discussed in detail. The resistivities are shown to be suppressed significantly by the renormalization from those calculated by using the RPA results for the spin fluctuations. Particularly the electrical resistivity can have a tendency towards saturation with increasing temperature.
