Abstract: We study the fluctuation-induced magnetotransport of a two-dimensional superconductor in the quasiballistic regime, where ξ GL(T) ≪ ℓ (ℓ is the electron mean free path and ξ GL(T) is the Ginzburg-Landau coherence length). The magnetoconductivity is evaluated in the nonlocal fluctuation regime thereby extending the existing theory valid in the local limit. We show that the Maki-Thompson (MT) and density-of-states (DOS) contributions strongly compensate each other and their sum is negligible in comparison with the Aslamazov-Larkin (AL) term. The hierarchy of the fluctuation contributions to the magnetoconductivity in the high-field limit is also qualitatively discussed.
