摘要：

We study the fluctuation Ettingshausen effect in a type-II superconductor using the time-dependent Ginzburg-Landau equation. The free-fluctuation theory predicts a divergence in the Ettingshausen coefficient at T=Tc2(H), in conflict with the recent data of Palstra et al. [Phys. Rev. Lett. 64, 3090 (1990)]. Including interactions through a self-consistent Hartree approximation eliminates the divergence and provides a quantitative explanation of the experiments. © 1990 The American Physical Society.
