Abstract

The semi-classical conductance of a two-dimensional electron gas is calculated in the presence of a one-dimensional modulated magnetic field with zero average. In the limit of small magnetic field amplitudes (B) the contribution of the magnetic modulation to the magnetoresistance increases as B^3/2 in the diffusive limit, while the increase is linear in B in the ballistic regime. Temperature does not influence the power law behavior but it decreases the prefactor of this functional behavior.
