Spin-fluctuation drag thermopower of nearly ferromagnetic metals
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 …
