Effect of anisotropic Fermi surface on the flux-flow resistivity under rotating magnetic field

Abstract

We numerically investigate the effect of in-plane anisotropic Fermi surface (FS) on the flux-flow resistivity ${\rho }_{\mathrm{f}}$ 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 ${\rho }_{\mathrm{f}}$ 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 ${\rho }_{\mathrm{f}}$ under rotating field.
