Strong magnetoresistance induced by long-range disorder

arXiv:cond-mat/9905364 · doi:10.1103/PhysRevLett.83.2801

Abstract

We calculate the semiclassical magnetoresistivity of non-interacting fermions in two dimensions moving in a weak and smoothly varying random potential or random magnetic field. We demonstrate that in a broad range of magnetic fields the non-Markovian character of the transport leads to a strong positive magnetoresistance. The effect is especially pronounced in the case of a random magnetic field where becomes parametrically much larger than its B=0 value.
