Abstract We extend our model of the flux-flow thermomagnetic transport coefficients of superconductors [A. V. Samoilov, A. A. Yurgens, and N. V. Zavaritsky,Phys. Rev. B 46, 6643 (1992)] to the pinning region. Using a method due to Vinokur, Geshkenbein, Feigel'man, and Blatter, we show that if the vortex dynamics in disorder-dominated,N/gr xx andS/ρ xx (whereN is the Nernst coefficient,S is the thermopower, and ρxx is the longitudinal resistivity) do not depend on the pinning strength. The theoretical consideration is illustrated by our experimental results on the high-temperature superconductors.
