The vortex motion and the related transport properties in unconventional superconductors are studied in the clean limit within the microscopic model following Caroli and Maki. Here we start from (a) quasi‐2D s‐wave superconductors and next move on to (b) quasi‐2D d‐wave superconductors where we mean by ‘quasi‐2D” the layered structured crystals or the case with a cylindrical Fermi surface. The diffusion constant which controls the vortex motion and the entropy carried by a single vortex are determined. We propose that the Nernst (or the Ettingshausen) effect will provide the most sensitive test of the present theory. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
