Effect of paramagnon drag on thermoelectric transport properties: Linear response theory
نویسندگان
چکیده
Paramagnetic materials exhibit a unique thermoelectric effect near the ferromagnetic transition point due to spin fluctuations. This phenomenon is referred as paramagnon drag. In this study, we calculate contribution of drag Seebeck coefficient microscopically based on linear response theory. Consequently, obtain general formula for and then clarify conditions in which enhanced single-band isotropic system. Moreover, coefficients mixture free-electron-like flat bands.

15 صفحه اولScattering theory of nonlinear thermoelectric transport.
We investigate nonlinear transport properties of quantum conductors in response to both electrical and thermal driving forces. Within the scattering approach, we determine the nonequilibrium screening potential of a generic mesoscopic system and find that its response is dictated by particle and entropic injectivities which describe the charge and entropy transfer during transport. We illustrat...
متن کاملMeasuring thermoelectric transport properties of materials
In this review we discuss considerations regarding the common techniques used for measuring thermoelectric transport properties necessary for calculating the thermoelectric figure of merit, zT. Advice for improving the data quality in Seebeck coefficient, electrical resistivity, and thermal conductivity (from flash diffusivity and heat capacity) measurements are given together with methods for ...
