Abstract
We numerically investigate the effect of in-plane anisotropic Fermi surface (FS) on the flux-flow resistivity $Ï_{\rm f}$ under rotating magnetic field on the basis of the quasiclassical Green's function method. We demonstrate that one can detect the phase in pairing potential of Cooper pair through the field-angular dependence of $Ï_{\rm f}$ even if the FS has in-plane anisotropy. In addition, we point out one can detect the gap-node directions irrespective of the FS anisotropy by measuring $Ï_{\rm f}$ under rotating field.
