Spin-fluctuation drag thermopower of nearly ferromagnetic metals

We investigate theoretically the Seebeck effect in materials close to a ferromagnetic quantum critical point to explain anomalous behaviour at low temperatures. It is found that the main effect of spin fluctuations is to enhance the coefficient of the leading T-linear term, and a quantum critical behaviour characterized by a spin-fluctuation temperature appears in the temperature dependence of the correction terms as in the specific heat.
