Title: Magnetoresistance of a two-dimensional electron gas in weakly modulated magnetic fields
Abstract: The semiclassical 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.
