Hall effect in the mixed state of clean superconductors
The Hall conductivity in the mixed state of a clean (l ≫ ξ0) type-II s-wave superconductor is determined from a microscopic calculation within a quasiclassical approximation. We find that below the superconducting transition the contribution to the transverse conductivity due to dynamical fluctuations of the order parameter is compensated by a modification of the quasiparticle contribution. In this regime the nonlinear behaviour of the Hall angle is governed by the change in the effective quasiparticle scattering rate due to the reduction in the density of states at the Fermi level. The connection with experimental results is discussed. © 1998 Elsevier Science Ltd. All rights reserved.
