Abstract

The off-diagonal component of the conductivity tensor of dirty type-II superconductors is calculated in the magnetic field nearH c2 . Contributions come from both the fluctuation and static parts. The former is the Ginzburg-Landau (GL) term, whose origin is the motion of Cooper pairs, and is obtained to the order ofT/e F as the result of the energy dependence of the density of states near the Fermi surface. The latter is obtained to the order of ω c τ. By use of the diagonal component of the conductivity tensor given by Thompson, Takayama, and Ebisawa, the derivative of the Hall angle with respect toH is calculated; it agrees qualitatively with the observed behavior.
